I have an IBM Lenovo T61. I've experienced a bit of "lagging" in terms of speed and response, most notably with regards to a 375-page searchable PDF file. The file is 128 mb. The computer currently has 2 gigs of RAM. My question is
a) Would it be helpful to add an additional 2 gigs of RAM (assuming T61's can even take that much) and
b) if you recommend a specific brand.
2 gig sticks are going for $38 on Ebay....
