Welcome, Google. Seriously.

Quite frankly, the more companies there are out there producing the next generation of superphone, the better. Plus somebody needs to push the iPhone team…because the Blackberry and Windows Mobile aren’t gonna do it.
T-Mobile is in a bit of a weird spot, given that their 3G is in a band nobody else in the world uses (1700 Mhz? Really?) but at least you get to reuse your 850 Mhz antenna. Sort of. (Honestly, I think it would have been better all round if they’d just given us two harmonics to begin with for mobile phones, but then, Europe kicked our ass up and down on the mobile phone front, so that ship has sailed.) But for the first time since the Pearl, T-Mob has a really compelling product that moves the bar and legitimately brings the Internet to your pocket in a way that Blackberry never did and WM6 never could. And let’s not even get started on how Symbian never took off in this country…
So welcome to the fight. Your move, Apple.
ETA: After looking over the reports and liveblogs, it looks like they’re going right for the gut on all the stuff the iPhone didn’t ship with: physical keyboard, contexual menus, 3G out of the box, wide-open developer program, etc. So now we get to see what’s doin’. I suspect that there may be some battery life issues at first, unless they’ve crammed in a much larger battery or Android does something truly astonishing with power management. (Pulling hard for the latter.) The fact that the phone will only launch in markets where T-Mob has already rolled out 3G, though, points up exactly why Apple skipped 3G in the first iteration of the iPhone.
