As you know I bought the HTC HD7 from T-Mobile and am reasonably pleased with it after almost 30 days. However, there are some quality issues with the hardware and I think it could have been much better. I just saw this morning that the 16GB Dell Venue Pro became available for purchase from Dell directly so I just ordered one for myself for $499.99. You can get the 8GB one for $50 less, but without the ability to expand the memory there is no way I would recommend that model. BTW, I found this Dell coupon code for 10% off that knocked the $50 off my 16GB model anyway, FMQLSTFF34SVV5. Keep in mind this coupon expires after 2,000 uses, but I was able to use it just a few minutes ago.
I am particularly interested in testing out the camera, QWERTY keyboard, and 4.1 inch OLED display. I held the Dell Venue Pro for a few minutes a couple months ago and like the feel of the hardware. I think it may be a bit unbalanced with the slide-up display, but I will let you all know as soon as it arrives. It is supposed to ship out by the 9th of December so I may have it in hand the 13th.
With new activation you can get the 16GB model for $149.99 and the 8GB one for $99.99, compared to the $449.99 and $499.99 without new activation. Keep in mind this will only work via 3G data on T-Mobile USA and not with AT&T. This is only the 2nd option T-Mobile customers have while AT&T customers currently have three choices.
