[Galaxy Tab 10.1 General] bilboa1:
I've and Ipad2. (also a SGT7, a SGS, SGS2 and only played around with SGT10.1)

Here are the issues/advantages, IMO.

Keyboard: It sucks. Can't thumb type easily. iOS 5 thumb keyboard is not much better. It's pretty difficult to type on it. On android, you can replace the keyboard and there are many very good ones.

Form factor: It's fine. I don't agree with the "tablet is to be used in landscape mode". The tablet is to be used in whatever position you f. like. Portrait is often a pretty good one. Don't assume crap.

Jailbreaking: it's not that simple. Yes on 4.3.3 it's one click on jailbreakme.com - but in reality, no other versions of the iOS are jailbreakable (not 4.3.4 which is latest, neither iOS 5 betas).

Besides you have to go through "complex" things to save special files so that you can jailbreak it again in the future, otherwise, if you upgrade to 4.3.4, no more jailbreak for you.

On the SGT this is VASTLY better.

Apps: yes, there are excellent, excellent apps and games, although, not as many as you'd like to think. Best apps are Apple ones, too.

99% of the useful apps are paid for, and generally more expensive than on Android. Even tiny apps that take 5min to code are generally for an euro with no free alternative somehow. That include apps you get on Cydia (excludes cracked apps of course)

There is also no "one click return policy" so you can't try the apps, you have to pay for them.

Finally, the AppStore is made so that it's terribly difficult to find apps (specially free ones) if you don't know them by name and search. All the category stuff will popup most expensive apps by default and the ratings are clearly biased toward that.

Lock in:

How do I install firefox on iOS? right, I can't.

How do I use Opera? Well it's not really Opera. It's Safari with the Opera skin.

Can I make an app to encrypt my storage? Nope.

Can I use a decent video player, such as VLC? Nope, it's GPL.

Can I use GnuPG to encrypt my email? Nope it's GPL.

Goes on and on. Android can do all that.

Bluetooth:

Bluetooth doesn't pair with 50% of my devices, @#!1&& crap. If you don't own an iPhone (and you are not jailbroken ofc), forget about it. Extremely bad point if you planned to use the iPad2 with your 3G phone, many just won't pair it. (or in fact, the iPad2 is the one not pairing here, the phones are just fine)

Browsing:

Flashless browsing is not so bad. Most sites propose html 5 videos by now and they work well. That said, from time to time, you do feel like you're missing your flash. Alternatives aren't as good as they seem. 99% of them decode/recode flash in the cloud (that works on android too btw, with like, skyfire). Local decoding works with jailbreaking only and it's very buggy.

ps: iswifter and the like display lower quality sites (compressed images) and are slow as f*. Don't believe the op. native flash > all.

Safari's wekbit is slower than Android's. In fact it's slower than Firefox mobile on Android. It's not _bad_ but sometimes you're waiting on the checkboard and that's not exactly a nice experience. Android webkit and Android Firefox never do that.

Sound:

I gotta include that one. The audio out is very good. The speaker is also very good (although not comparable with the audio out).

Other devices rarely come close to that quality.

Battery life:

it's seriously on par with Android.

General OS feeling:

Where's my return and meny key? How do I know where to tap on the screen to bring up a menu/return? That's right, most often you just dont. You try to tap around the top, corner and bottom and hope. Most apps don't put buttons for that, it's just guess work. Android does that WAY better.

Where's my multitasking? Well, except the fact that double clicking the home button is more annoying than single clicking it for a longer time (android), both iOS and Android multitasking is horrible UI design.

WebOS, Meego, Win7 are far easier there.

Note that iOS gets push notifications right: every app uses them and you're asked to allow them every time. I can't count how many Android apps don't even use them and keep data open at all time on separate servers, and how many of the ones who use them cannot be disabled without uninstalling the app completely.

One of the reason why android feels like it uses more battery while in fact its just poor apps which bring everything down.

Finally, do I wanna switch to a SGT?

Hard to say. If garageband was available on the SGT I think i'd switch easily. So yes, a couple of apps are enough to keep you on the dark side. If the SGT's OS was better (read if Android was better - or if meego ran on it?), I think i'd switch too.

For now, I'll probably wait for the next round of tablets.
