I agree, I wish it came with 2 GB of RAM (not much more you can ask for in the ARM world right now). There are actually a couple of Lenovo and Toshiba tablets with that much RAM that have been announced, but they don't have an integrated keyboard like the Transformer.

As I said, you might want to wait a few more months otherwise. The next Transformer should come with 2 GB of RAM, 1920x1200 resolution, and might even have a 11.6" version (but just totally speculating here, based on how Asus might think for a future device).
