if you dont care about the slide out keyboard then you should wait for the bionic. it should be released pretty soon in the near future. but if you absolutely can not wait you should look into the x2. that's just my opinion. coming from a very satisfied tbolt owner.
what is the bionic going to have over other phones. Is it basically a 4g LTE version of the x2? I've read a good bit speculating it may have this or that, but nothing reliable.
It's basically a 4g version of the D3 with a larger screen, no keyboard, and more RAM (dedicated to webtop). They both (D3 and Bionic) will have the OMAP 4430 processor, the x2's processor, is not as good. The both phones have qHD pentile screens and will function the same as the x2 (and thus are very readable in direct sunlight).
Everything I've read says Bonic will have an nVidia CPU not TI.
Those are the specs for the original version of the Bionic that was scrapped (the "Etna"), not the one that actually will be released. All indications are that the Bionic will be released with a TI like the Droid 3.
