The Atrix has 1024 GB w Tegra 2, the TBolt 768 with 1 GHz CPU and the Bionic 512 MB with Tegra 2. These are all the best spec'd phones released from Feb '11 to Apr '11, i.e. they are the best gadgets of teh top two cell phone carriers. For my desktop I preferred a slower CPU (i5-760) so that I can afford 8 GBs of RAM, which I felt was necessary for many tabs and programs to run all the time. Obviously Android uses memory differently. How much is needed? My D1 with 256 MB of RAM is slow, though I wonder if that's also related to the older GPU. Thanks!
