Macs are great, but you pay for the experience and they are a little slower (they used to be much slower when PPC, but the new core-duo Intels bring them closer to Windows speeds).

Currently the Mac Pro systems run about $2000 and up.  You can get a good iMac Intel for about $1500, but there is no room for future expansion there (or in the MacBook or Mac mini).

Then there is the consideration of software.  Yes, you can run Windows virtually (BootCamp or whatnot), but I don't subscribe to that unless you intend on using the MacOS and software at least 50% of the time - otherwise, it's a very expensive Windows emulation system.  You can get more power for the same money in a PC system.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
