Take 2 on expanding my memory... thank goodness for lifetime warranty... I had some problematic Patriot memory, and ended up RMAing it. Patriot took less time in replacing it than my procrastinating in actually shipping it back. My home box, which was already expanded from 2 GB to 4 GB earlier this year, got bumped up to 8 GB last week. It feels that my copy of Vista 64-bit is finally more usable now than at 2 GB. Of course, my primary OS is still XP, and my box can't recognize more than 3.5 GB under XP. As for my laptop... it was already maxed out at 1 GB for years. So, the question becomes... how much memory is in your primary Windows box?
