I've replaced dead hdd in my dv1013us yesterday,
installed xp sp2 on hd160hc and guess what?
it fits in under 100 megs of ram.
granted, i could make linux run on less than 16 but with xp you get a
user friendly os
and media buttons work. gonna install hp slugware to bring memory
usage to 200 megs
so that I don't feel too bad looking at the activity monitor system
memory page:
writing this from a last gen 8mb 17" macbook pro
running 10.7.2 bloatware solely so that xcode can work
(strangely xcode 4.2.1
is just a tad over 300 megs today.
4.3p3 looks pretty good also stability wise
not sure who got whacked but it seems to solidify, gradually)
