Still considering the Mac thing. I'm quite decided to get a 13" MacBook Pro. However I'm unsure how necessary or interesting is upgrading it from 4Gb RAM to 8Gb. The upgrade costs more than 500 euros. I know it would be possible to do it myself, but I'd probably void the warranty, or it's possible it's not that easy and I end up screwing it up.
I will mostly use it as music server feeding the DA11 by USB, some web surfing and eventually, if I get some AD converter (perhaps a Duet or the like), making some vinyl or FM rips. Probably no video duties. Is still 8Gb RAM "that" worth the cost?
In any case I'd get it with a 500Gb HDD, though I'd keep the music library on an external USB HDD or I'd try to set up a wireless LAN so the laptop can use the files already stored in the main PC. Hopefully shaking hands between a XP PC and a Mac isn't impossible. Completely new to Mac OS.
Any comments and advice will be very appreciated.
