Overall User Rating (4.1 Out of 5 based on 158 ratings)
Overall: It's probably the best productivity tool out there, in tablets that is. UI is superb. Hardware top notch. There is no perfect tablet out there, so depends on whether this fits your needs, but i must highlight that this product is extremely well made.
Big problem with PB has been choice of apps, which has started to change over the past many weeks. Also, with the 2.0 OS expected in Feb 2012, it'll be compatible with Android app world, which should address the problem. Having said this, it already offers a lot of relevant apps.
Gaming experience is excellent. I've played games on ipad, and samsung tab. PB is miles ahead on gaming experience. One needs to check out the list of games available on the app world....it's impressive.
I think PB was not appropriately positioned by RIM. They should have targeted the existing BB users first as there was a strong association with the product already.
Another issue is bad press. Due to poor off-take of this product globally, PB has become a favourite whipping boy, but as a user for 6 months, I am glad i bought this product. I'm not into a lot of gaming (my son is hooked!), but experience of integrating mails, calendars, notes, browsing (all via tethering) is very good. It's browser is superp too.
QNX (now called BBX) OS is a pleasant surprise. I think it's miles ahead of competition, the power of which (hopefully) will be seen next year with the major OS upgrade (expected in Feb, fingers crossed).
Lastly, camera is high quality. I've stopped using my standalone camera completely. It has a capability to record in HD and the results are excellent again.
And oh, PB supports flash (i know Adobe has announced discontinuation of flash, but dont forget how proliferated flash usage is on the web). Watching videos, movies, etc. is a joy. HDMI connectivity also lets you mirror on TV which means PB becomes your controller for a game, or a remote for movie. Due to its wifi capabilities you can stream movies directly to a connected TV.
I know i may be sounding a bit biased (as an owner already), but the idea is to provide as honest review / opinion as possible.
Hope it helps!
