hello

i have used most of them and i totaly disagree with your statment about restriction on IPad, since you can easily jailbreak your Ipad and install Cydia and 3rd parity applications hassle free.

Any way the question should be whats your main requirments before you need to purchase any tablet

below is examples:

IPAD2 : all purposes, business, video conferencing, GPS with offline maps, multimedia and web browsing plus more then 600,000 applications many of them is impossible to find on any other device, e.g. airvideo where you can stream and watch any video with live conversion without the hassle of codec

9 continues hours battery life, amazing feature nothig beat it.

one of the other important factor is the accessories for IPAD their are thousand of accessories and things you can buy for ipad and almost 2 or 3 options for any other competitor item, this give you as client lots of options to use your tab in many purposes

Great email options: love it and syncing with Exchange especially contants and calender is amazing, you can do this now usng Google and Hotmail as well

Cons:

Flash: is not embeded feature, however you can install it from cydia

Itunes: syncing with Itunes is hassle for some people at the begining, Itunes is good product however their is some difficulties to learn on it

Android tablets:

the best between them is Motorolla tab, i have used it for a while and its very nice tablet

good for web browsing, multimedia and games

Business: Big question mark on this, i have find it very inconvinient and Android market is not fully stable in comparision with apple

Games: there is some good games out there, but most of them is crappy

Multimedia: not bad, however codecs is a hassle, and you will have problems

Emails and exchange is not bad

Battery life about 4 hours

GPS: online version, and Sygic is not that good on it, i wont recommend it much

Limited accessories

Blackberry tablet:

about 7", boring, nothing good about this tablet, i ended up selling it after 3 days from buying it.

No application, and if there is applicatons it will cost fortune, unlike apple store where most the apps cost less then 1 USD

you will need to own BlackBerry and pay monthly subscription to use this one, not convinient and size do feel wiered in hand

 

I'm not going to influence you on any of these tablets, but my recommendation that you are making a wrong judgment based on faulse information, you need to rectify your information about this product and i'm sure that this might be one of the best advices you will get if you listen to me :)
