My friend told me yesterday, 15" PBook with 1Gb(1 pc 1028 RAM)
for $3,888.
He didn't check for 12", but my advise is don't go for 12", bad for
your eyes if you're going to stay long with it.
I'm starting to squint my eyes doing graphics for straight 12hrs
even with my 14" laptop.
To compare weight and comfortablity to eyes, i think i'll choose
the latter. 
But if it's me and the 15" Pbook with the gorgeous 1Gb RAM(You can
check original price in apple.com.sg) I'll whack!
