I am going to try upgrading the memory in the LX195 as that appears to be least expensive solution. (at least potentially) I have creditcard rewards points and here's a 2GB memory stick I can get for free. PNY - Optima 2GB PC2-6400 DDR2 DIMM Memory Will this work in the LX195? I've been confused on max upgrade/memory speed based on reading past posts. Please help. Thank you.
