I've been having fun playing with an Acer A500 Honeycomb tablet lately and comparing it with the iPad my company got me last year. Both are WiFi-only.
I've been using the iPad heavily for over a year so I've gotten to know it inside & out. I'm still pretty new to Honeycomb, been poking around on it quite a bit and learning to write Android apps, but still have more to learn.
EDIT: 9/23/2011: I bought an Acer A100 about a month ago and have been using it heavily. It's essentially the same as the A500, except for the 7" screen (smaller footprint) and it does not have a full size USB - it has micro USB only.
These are my observations.
OUT OF THE BOX EXPERIENCE
Summary: Acer wins this category, hands down. The iPad out-of-the-box experience is absolutely horrid.
When I first got my iPad, the initial out-of-the-box experience was so incredibly bad
I was absolutely stunned.
In short, your newly purchased iPad is a brick until you
install iTunes on a separate PC, open an iTunes account, give Apple your credit card number, and tether the iPad.

here.
Can you imagine if any company other than Apple required you to give them an open credit card number
just to use the product you just purchased from them, even if you don't intend to buy anything else?
The Acer experience was much better.
First, it works straight out of the box. Simply turn it on and start using it.
You do need to create a Google account, but:
I downloaded a few apps from the Android Market and it still never asked me for a credit card. That's as it should be, because they were free apps. With Apple, you can't even download a free app unless you give them your credit card.
Next I installed the Amazon Android app market. This is another thing I like about Android: an open system. Multiple companies and app stores all competing for my engagement and business. The Amazon app store has a free app of the day and I check it regularly.
So far, I've gotten a nice print app that normally costs $15. It's easy to use and works well. I'm sure it's possible to print with an iPad, but I never did get it to work. It's much easier and simpler on Android.
HARDWARE / CAPABILITIES
Summary: A500 wins this category.
The Acer has all the capabilities the iPad has, plus:
MAPS
Summary: The Maps app is better on Honeycomb than it is on iPad.
Several ways Maps are better:
THE BROWSER
Summary: The built-in Honeycomb browser on the A500 is faster, easier to navigate, gives a better more customizable web experience, and works with more web sites.
For most people including myself, this is the most often used app.
After over a year of frequent use, I have some pet peeves with the Safari browser on my iPad...
namely:
Now for the Acer A500 browser (the default built-in one):
STORAGE
Summary: the A500 has more storage options and capabilities.
Here, the iPad is simple: you get what it comes with. It doesn't accept SD cards and has no capability to access external storage devices. You can purchase an external SD card reader from the Apple store, but it plugs into the iPad port, so it's hard to take with you. The A500's storage options & capabilities are:
Another form of storage that Apple doesn't mention in their specs is RAM: Random Access Memory. The 16/32/64 GB of memory normally advertised is CMOS, not RAM. It's not as fast as RAM - running programs use RAM not CMOS. The iPad 1 has 256 MB RAM, iPad 2 has 512 MB, the Acer A500 has 1 GB RAM.
I suspect that some of the iPad browser's annoying quirks, such as unnecessarily reloading pages when you jump around, are likely related to its limited RAM - it doesn't have enough to cache pages in memory.
STABILITY
Summary: iPad wins this category.
Apps occasionally crash on both iPad and Honeycomb. But it happens more often on Honeycomb. This is likely because Honeycomb has only been out for about 3 months, and unlike iOS, it runs on different hardware platforms and each vendor is responsible porting Honeycomb to their platform.
NOTE: just one month later, Honeycomb is already better in this area. It's now not quite but very close to iOS in stability; the difference is quickly becoming moot.
When an app does crash, what happens on iPad & Honeycomb is similar but not the same. On iPad, the app simply disappears and you seen the home screen. On Honeycomb, this happens sometimes, but usually a window pops up enabling you to send feedback about the crash. If you don't want to, just hit CANCEL and you're back to the home screen.
BATTERY
Summary: iPad is a draw with the A500, but both of them beat the A100. Honeycomb provides better visibility and control over what is consuming the battery.
The iPad has the edge on the A500 in battery life, but only when the A500 has "background data" enabled. Both devices give me a full day of use, but the A500 only barely so. The iPad typically goes for nearly 2 days of use. Since both give a full day, the difference is not an issue as long as I remember to charge the A500 every night.
One contributing factor to this is Honeycomb has true multitasking: browser page loads, file downloads, application updates, GPS and other tasks run in the background while you work. The iPad makes you sit and wait for them. If I turn off "background data" on the A500, the battery lasts as long as the iPad. And this is a fair comparison, because that's how the iPad works - there is no background data capability.
Battery life on the A100 is poor - about 5 hours of continuous active use (like watching movies over WiFi). Even if it mostly sleeps during the day, you must turn off "background data" to make it through. With background data turned off, it goes about 10-12 hours of on and off mixed usage. That's enough to get through the day, but only if you're not using it heavily.
The iPad can also trickle charge when connected to a sufficiently powered USB port. The upper right screen will say "Not Charging", but it really is - just very slowly. This is a nice feature that the Acer tablets don't have.
One nice feature in Honeycomb is detailed metrics about battery usage. It has a very cool time graph showing when it's been awake and asleep and charging, and exactly what % of the battery so far has been spent on which hardware & applications. For example, after a day of usage, mine's currently telling me:
This is very useful if you want to know what's actually using your battery, and what to do to extend battery life. For example, I might consider turning off BlueTooth, but this tells me it would only save 2% of the battery, so there's no point. But turning down the screen brightness or shortening the screen inactivity timer might be a good idea.
TETHERING
Summary: A500 does not require tethering and iPad does. And if you want to tether, the A500 is more flexible.
Here are some of my pet peeves on iPad tethering:
Now for the A500:
NOTE: the A500 uses mtpfs for the USB. This should simply work on Windows & Mac. Linux requires an mtpfs driver, which are freely available and easy to install (e.g. "apt-get install mtpfs").
USABILITY
Summary: Honeycomb / A500 wins. Both iOS and Honeycomb are intuitive and well designed, but Honeycomb has a superior notification system and better keyboard experience.
You can set up both devices to launch any application you want in 1-2 touches. Both have equally responsive, easy and intuitive interfaces. Both have all most-used functions one or two quick easy touches away: context-aware "back" and "settings", app switching, screen brightness, volume controls, orientation lock, etc.
The key difference here is notifications. Apple's notifications are system-modal. They interrupt EVERYTHING you are doing and FORCE you to respond. This is especially bad if your iPad has been turned off for a while and you turn it on. You could spend the next 5 minutes touching OK on a long stream of notifications before you can use it.
Honeycomb notifications appear in the bottom menu bar. They are not modal, you can ignore them as long as you like. You can configure an optional sound or vibrate to accompany them. When you touch them they pop up into the message or app as you'd expect.
Another area Honeycomb has an advantage is the keyboard. I type about 100 wpm on a good keyboard, a bit slower on touch screen keyboards, but iOS is constantly interpreting my typing as other gestures. One moment I'm typing away and then suddenly the entire keyboard disappears and the screen zooms in. Apparently, I hit 3 keys rapidly enough to make iOS think I did a 3-finger tap. There may also be other gestures that are confusing iOS.
This doesn't happen on the Android keyboard. My guess is that Android isn't overloaded with as many hidden gestures as iOS is. Also, the Acer works well with a variety of BlueTooth keyboards.
APPLICATIONS
Summary: iPad wins this only by a nod, with more high quality apps. In another 6 months I expect this category to be a draw.
The iPad has been out for more than a year, during which time it's been the only real tablet on the market. And the selection and quality of apps shows this. Honeycomb has only been out for 3 months and the app selection shows this as well.
That said, Honeycomb has a handful of impressive apps that take advantage of its greater capabilities (higher video resolution, faster processor, GPS, etc.) and these apps are better than the iPad versions. For example, Google Maps, Google Earth, WeatherBug, Sprinkle to name a few. There's just not enough of them ... yet.
Another point in Honeycomb's favor is it handles different screen resolutions better than iPad. If you run apps made for older phone versions of Android it scales them smoothly to the bigger screen. The iPad just shows a tiny little app in the middle of the screen. You can 3-finger tap it to make it bigger, but it only scales 2:1.
