A brief note about "virtualization" a la Parallels:
This ain't your father's virtualization. If you've ever used Virtual
PC, it's similar only in convenience. But in performance it's in a
whole other universe, effectively redefining what virtualization means.
In the olden days, virtualization had to take place at the lowest
levels, translating every machine instruction one by one, millions of
times per second, from the Intel instruction set Windows is written for
to the PPC set it was running on under Virtual PC.
But on Intel Macs, there's really very little being translated at all.
Machine instructions simply get passed right through to the Intel
processor, and only a small handful of operations regarding peripheral
devices (CD, Internet, etc.) require any remapping at all.
So in terms of compatibility testing I doubt there's much difference
between Parallels and Boot Camp. But in terms of convenience they
couldn't be father apart:
The one thing Parallels does that's similar to Virtual PC is allow
folders to be shared between the native Mac OS and the Windows OS
running inside of it. This means you can easily assign a development
folder to be shared with Parallels, and work on it in either OS
simultaneously. You can make your builds on either OS and run them in
the other -- no reboot necessary. You can move from one OS to another
effortlessly, without stopping anything you're doing in either.
Sharing folders and running the OSes simultaneously means an
order-of-magnitude productivity boost over the quit-reboot-start-over
routine required with Boot Camp.
Parallels is so superior in terms of workflow I'll gladly put myself out
on this limb, just as I did years ago when I first suggested Apple would
one day switch to Intel: I predict that not too long from now Apple
will acquire Parallels, and ditch Boot Camp altogether. Stranger things
