#1, build quality. It has the same sharp unfinished edges problem the original Pre had, meaning that moving from Palm to HP hasn't improved the build quality. HP didn't have a good rep there to begin with.
#2, resolution. XGA doesn't cut it at that size, HD resolution minimum, 1366x768 ideally.
#3, screen quality. A tablet is pretty much all screen, they shouldn't be skimping. Not unless it's ultra cheap.
#4, size. The PlayBook showed that 7" is pretty ideal for that form factor, at around 10" I'll wait a year for the Asus Transformer 2 running Windows 8.
#5, fingerprint magnet. It's a horrible idea, companies need to be punished for putting out so much crap with glossy plastic.
The word 'Pentaband' means '5 Bands', from the Greek word 'pente' meaning '5'. For a phone to be pentaband it has to support 5 bands. If the phone has AWS support, it doesn't automatically mean that it is pentaband. The reason Wind and Mobilicity users like pentaband phones is because the reverse is true. We're not the only ones who like pentaband phones though, so please stop referring to phones that work on Wind and Mobilicity as pentaband. It causes unnecessary cofusion.
