When I get a new PC it'll be Windows 7, but what are the pros and cons of
the two different bit sizes ?
Pros of 64-bit Windows 7:
1. Can run genuine 64-bit applications (but there are very few of those).
2. Can support a larger amount of physical memory (maximum 4 GB on
Win32, up to 192 GB on Win64 depending on version).
Cons of 64-bit Windows 7:
1. Can't run any 16-bit (DOS) programs - other than using a emulator
like DOSBOX.
2. Poorer support for legacy device drivers: if you have an older
scanner, printer, camera etc. 64-bit drivers may not be available.
3. 32-bit applications run under the WoW64 emulation layer:
compatibility is good but not 100% and a few programs may not run properly.
On balance I generally recommend the 32-bit version, but YMMV.

compare and contrast with Linux/Mac OSX where "on balance I generally
recommend the 32-bit version" became the reverse about three years ago.

that they know how little is really possible -
and how hard it is to achieve it.
