Macs are supposed to be good but their spec per pound is much worse. Are they worth the money? and are they any good for recording?
Macs are excellent for recording -- they've had a good rep in this area longer than PCs and not without reason.
Many of pros use Macs, sketching out demos in the tour bus on GarageBand and then migrating the project to GB's big brother Logic (the full version of which is extremely serious music production software).
Some of the main advantages of Macs are that you don't run usually run into weird hardware and driver issues, there are very few security issues, and still
no (zip, zero, nada) known viruses on Macs. (I've a friend who works in a climatology research institute, and their IT guys recently decided all new machines are Macs because they were wasting way too much time trying to keep Windows machines from getting corrupted.)
Mind you, I've been a Mac fan ever since I had to make a choice about which GUI-oriented system was going to replace my 286 machine with DOS :) but I've experienced all the joy :? of Windows with machines I've used at work, and I've
never regretted using a Mac as my personal machine. You pay a bit more at the outset -- but, if you compare features, not actually very much more -- and I think the savings in ease-of-use and maintenance ends up being more than worth it.
Your mileage may vary, of course, but that's my tuppence!
