To those helping me out on that other thread, thanks a lot -- I ended up going with the R15 and I'm loving it so far. But it does need more RAM. I was hoping you guys could help me out with a few more questions: (1) I think the FSB on the R15 is 400 MHZ, but it only comes with 333 MHZ PC 2700 RAM by default. When I upgrade, can I put 3200 in it, or will that not work? (2) If I do the upgrade myself, will that invalidate my warranty with Toshiba? (3) Is there much different between generic RAM bought off of Pricewatch and "name brand" stuff?
