Quick comparison:
TB
*Better dev support (if low level or non-rooter, this is not an advantage)
*4G
*More ram (few hundred megs, but Android 2.2 and higher can fill that up too)
DX2
*Far more powerful and as good or better battery life (when TB is switched to 3G mode, else the TB can be bad with battery). Test N64 and FPse PSX games. No comparison. Games that choke on the TB are smooth on the DX2.
*I thought the TB had a good display, but the DX2 is far better. Better contrast and brightness. Though a pentile display, the higher res offsets this. Looks better than the Atrix and reviewers point this out as well.
*Better reception with phone, data and wifi radios (sans 4g of course)
*Better build
*Fits easier in the hand, due to shape (easier one hand operation)
Shame Tegra 2 did not get along with VZW LTE radio chips.
Can we finally put to bed this "not optimized for dual core" crap?! Dual core is better and faster RIGHT NOW!!!! :icon_ banana:
