Heh,
On this 500mhz g3 ibook, virtual pc 5 is dead slow (probably due to osX, bvadr), but it appears to emulate everything flawlessly.
I have found that I do not need any windows applications, except for my net banking which requires a c: drive (yes, they are very smart at the bank).
You do not really need windows or its applications either - there are plenty of alternatives, if the specific program is not already made for the mac, and if you really, really, really need it, use virtual pc and it should work - just slow (here, at least).
Go tell him to buy an a1 and run macos on that instead :-)
Sincerely,
-Kenneth Straarup.
