Quite a few people I know are now switching to Macs... (not airs) because hardware and software are well integrated (ahem)

But also because Parallels works relatively well and allows Windows Integration in a nice way. People like the Bells and Whistles which come as standard with Macs which dont exist on simple Windows platforms. Multi-finger touch pad functionality seems to be the main hardware advantage; and easier approaches to installing / removing software.

Does it make Mac better? Not necessarily, but it is refreshingly different, novel and no longer in the realm of niche products. "It just works" - well maybe (maybe not) - but does it with style.
