Any laptop can play music, even if it has the lowliest Atom processor.
But why not try in the shop before you buy? Just take your terabyte hard disk with you and use the built in music app to play a track. Any mp3 should do.
I have a very large music collection. I've always used my 120 GB iPod Classic to Play a portion of it through my Bose iPod speakers, a regular stereo system or via USB directly into my car stereo. I have wide-ranging tastes and I keep on adding songs to the iPod. I've almost maxed it out. The solution I have in mind is a small as possible laptop that I can install iTunes on, and hang a portable multi-terabyte disk drive on it that loaded with all my tunes.
My question is what the least processor that would effective for this kind of use? It appears that most of the sub-15 inch laptops have Celeron, atom and even Pentium processors. Would any of these do, or is the lowest end I should consider an I3?
I'd like to keep the price as much under $500 as possible.
Any comments or suggestions would be welcome.
