How much RAM do we realistically need to run Windows XP with Parallels on Mac OS X, possibly on Macbook? I guess the answer depends on how much RAM you allocate to the guest OS of Parallels, but my mac mini at home has 1GB memory but with a couple of memory hoggy apps running (iTunes, Safari, Miro, VLC, iStat pro etc.) the behavior seems to get a bit laggy these days. For a reference, here's the top result:
SharedLibs: num = 195, resident = 35.8M code, 4.52M data, 9.62M LinkEdit
MemRegions: num = 10825, resident = 273M + 16.2M private, 85.4M shared
PhysMem: 259M wired, 451M active, 299M inactive, 1010M used, 13.3M free
Since my work laptop (ThinkPad X40) is almost dead, I'm thinking of switching to Macbook. I definitely want to continue using Windows XP and some apps on it. Also, would like to know which model you recommend ... I can't carry a heavy laptop that weights more than 2kg :) 15.4" MacBook Pro maybe?
