I've had a few days.
I like the interface MAC OSX tiger refreshing compared to XP.
I love the lair of the beast, customizable at will and so easy to upgrade. An happiness! The interior of the unit is separated into drawers. Everything is simple and nikel access even for the uninitiated.
Mighty Mouse is not very accurate at first sight ... and ergonomics is average (although it does not take in hand, too round, and the side buttons are hard and the only button (hull) top is destabilizing.
I've tested the Mac Book ... G4, G5 ...
1024 MB RAM is a bit lighter. To upgrade essential.
The value for money ... Hmm ... The prices could fall! We pay the brand, of course, in addition to the excellent quality of all ... But still, it's price to pay!
I'll see if I use with Cubase Studio 4 is ideal. Ral I had a bowl of PC Fair (even with Cubase LE !!!), all offset projects, completed mixes and impossibilities of export.
In short, I chose Mac for calm (my PC makes a noise microwave) and stability.
I hope to keep it long and upgrade over time, not to show off and be at the forefront, but not to feel limited in my work.
