Down to two choices..

[plac]

Either the Sony with a better CPU and better resolution, but hard soldered 128GB of drive space, OR The Envy, buy a 256GB SSD for it, and still be into it less money than the Sony.

how big a difference does that 1366x768 to 1600x900 really make? Is the Envy's graphics chip also better? I think it is.
