Me have already addressed many people if I do not "too big / bulky / heavy" find the device, but I was able to answer all these questions with "No". In my eyes, it's almost perfect. Clear, to call the size is not very suitable, but even that is possible. In addition to such a device can not be bought to make phone calls. But I still have a second mobile phone in use.
For everything else, the Streak is responsible. I think I would even do without a laptop. Mail, Facebook, Games, Whatsapp, movies, music, pictures, etc., are not a problem, but the pure enjoyment in the 5 "display.
But pity is the outdated Android version. While working properly and a bug to me so far not encountered, but still lacks some cool features of the later versions. But who bothers arg, which still has the ability to root his streak. I habs not yet done, I'm quite happy with 2.2 :)
All in all, recommended the Streak for all people who are not bothered by the enormous size: D
