My current iTunes library is on a PC that I share with other people. The computer is rather slow and processes on iTunes are taking much more time than they should. I was thinking of buying a macbook but wasn't sure if it would be able to hold my iTunes library which has almost 3,000 songs and a good number of apps. Would the macbook be able to hold my iTunes library and would it be able to do so without making the macbook equally as slow as my PC?
