4 GB of RAM is more than enough. You probably won't even notice the difference with 2 GB.
By the way, you need a 64-bit OS if you want to use more than 3.5 GB.

Hi guys,
I'm comparing thin and lights, and the Asus UL models have the Intel Pentium 7300 processor with a max of 4gb of ram, while the Toshiba s105, which is $300 less has the 4100 processor, with 4gb of ram but a max of 8gb.
I don't need a powerhouse, but am curious if the extra 4gb of ram would equate to approximately equal performance in tasks like email, basic photo and video (Picasa and Flip). From a budgeting perspective, I like the idea of buying cheaper now, and then in 12 months time or so purchasing the extra RAM.
