Self,
You didn't tell us very much about your friend.
OK, that felt weird just typing it, but I digress.
What's he play?
Is he a; Beginner, Student, Professional?
If I'm supposed to guess what the computer's for, I'd better get started. The musicians I know use their computers for a whole bunch of stuff.
Transposing/writing/arranging?
Creation?
Editing?
Keeping track of bookings?
Buying slide trombones on e-Bay?
Doing a backround check on the new keyboard tech?
Downloading audio for sampling?
Posting to his fan site?
Organizing his ever growing collection of internet art?
Vanity searches on Google?
Making demo CD's?
Making music videos?
Writing lyrics?
Testing the DRM Sony BMI created for his "Live album"
Wait, I got it!
All of the above?
Good choice! Your friend sounds like a real musician, so for today let's start with earning a living. It's important.
While there are probably good music applications for Windows, I don't know much about them. Most of the musicians I've worked with for the past few years, use Macs. At least, that is, the ones who use their personal computers to make money. There are musicians who just use them for e-mail and looking at umm ... art. Yea, art on the internet. Some of those have PC's, but who wants to play the slide trombone for a living? (inside joke)
I am not a musician, and I've never wanted to play one on TV, so all my knowledge is observational. I have, however, spent 26 years working with musicians. Well, ok, not really working. Most of it was spent in the back lounges of Eagles, Prevosts, and the odd ''double decker'' watching movies and playing with computers on the way to a gig.
To the point.
ProTools, Reason, & Logic Pro, are the titles I've seen most often. As I understand it, Garageband is a simpler version of Logic Pro. It's also FREE.
Every time I hear the name ProTools, the word "Plug-in" is somewhere within a sentence of it, so I guess your friend will want to get some of those.
Reason is just really cool, even if you don't know how it works. I could play with the virtual patch on the back of the virtual rack for hours.
Real time audio manipulation of multiple tracks takes lots of RAM. Now is not a good time to be cheap. Tell him to pass up the sousaphone he saw on e-bay, and get RAM. Also, as the number of tracks goes up, your friend will need a fast hard drive, but RAM first.
What else can a Mac do?
In the past five years, I've seen macs driving midi keyboards, and backing up their sound settings, Controlling SMPTE time code, and playing extra tracks to fill in the sound, producing click tracks for drummers with short attention spans, and lyrics for singers with short term memory loss. I've used my Powerbook to run a two hour Vegas show with over a thousand dimmers and fifty "moving lights", when the Hard drive in the lighting desk crapped out twenty minutes before curtain.
I know a bass player that makes extra money in his hotel room laying down studio tracks. Recorded tracks are sent to him using iChat, through AOL IM. He adds his tracks using ProTools, and sends them back to the studio. These are VERY large files, so a broadband connection is a must, but AOL IM and iChat allow transfers of any size.
FOH & monitor engineers are still on Windows, but that's changing, as Mac software titles are released to interface with the cutting edge pro digital desks. One guy, that I know well, has been checking the web every week, waiting for that last critical piece of software that will let him say goodbye to Windows.
I've noticed that most people on the road doing work and making money with their Windows laptops end up not using it for anything else. They carry a second computer for personal stuff, and the ''work laptop'' becomes another piece of gear for the back-line guys to maintain, and pack into a road case after the show.
I guess they figure that using a Windows machine to surf the internet, do e-mail, use WiFi, and deal with spam, is too much risk to a piece of gear they depend on for a paycheck. Can't fault them for that, but I'm also guessing your friend can't afford two computers
Another observation.
When Murphy happens, and a Windows laptop breaks/crashes/''fails to function'' (usually just as the opening act walks off stage, because, Hey! it's Murphy!) the troubleshooting path usually becomes ''try to fix it'', and at the same time try to figure out how you are going to do without it if you can't fix it. I don't know much about Windows, and honestly don't know why this is,
Because...
When Murphy happens, and a Mac breaks/crashes/''fails to function'', it will still happen at the worst possible time, because ... yep, Murphy.
The troubleshooting path is different though. It still starts with ''try to fix it'', but at the same time it's ''go tell the T-shirt guy I need to borrow his Powerbook''. ''I can boot it from the back-up drive and still have time for a beer/cigarette/groupie/high colonic/prayer (depending on the band) before house lights go out''.
This is not a scientific survey of all musicians, or even of all musicians on the road. These are observations from the lighting desk. My best hope for showing musical talent is coming up with a good iTunes play list.
YMMV, know what I mean?
