Wondered if anyone had feedback on the Sony Vaio SA laptop (1600x900 screen resolution, i5-2410 processor and an AMD 6630 gpu)? I'm leaning toward purchasing this laptop due to its great battery life and mobility, but wanted to also ensure I was able to enjoy SL at the same time. Does anyone have any thoughts they can share on using this laptop with SL? Also, many have said the most important part of a good SL experience (besides the company) is the best gpu you can can afford. This particular laptop max's out at the 6630, but I could also **maybe** afford to an upgrade the processer (i7-2620), both are dual core, so I wondered if the $250 dollar difference was worth it. Thanks for your thoughts.
