According to TmoNews, the Dell Streak 7 has a release date of February 2, contrary to reports about the device coming in January by Engadget. No information about pricing at this time.
The Dell Streak 7 carries Android 2.2, Nvidia Tegra 2, a 7" 800x480 capacitive screen, and T-Mobile bands. We have yet to find out if we can make phone calls on this device.
Nice but I bet it will cost a fortune. Plus you'll have to add voice and data to it. If you could do a data only line it might be worth it but that turns out to be a costly tablet in the long run.
