I have a Dell Streak. I've had 9 of them over the past 9 months. Maybe 8, I've lost count.(And kudos to Rogers Wireless customer support for finally getting me one that's okay and also waiving my 24 month HW upgrade fee.)

I've had 3 new and the remainder have been refurbished models. Problems that have occurred:

1) Batteries not included. 2) PDMI cable not included, just a microUSB. 3) Screen tinted blue. 4) Dead pixels. 5) Vibrator damaged. 6) Accelerometer sluggish changing values. 7) Case peeling off in lower left corner. 8) Poor WiFi connectivity 9) Refusal to wake-up/power-off 10) Unlock slider resets mid-swipe, unable to unlock phone without fiddling with the power button and retrying several times.

and

11) the ubiquitous back panel issue. It falls off, especially if in pocket. Coupled with issue #9 you need a pair of pliers to regularly bend the tabs so the back panel will 'snick' into place and stay there.

It's been pretty useless as a phone. But I use it as a testing device. If an app works well on the Streak...

Also, in airplane mode (with WiFi on) battery life is really good.

DoD has to buy American if they can, but these things can't be relied upon.
