I have a modern Windows laptop which serves me fine for what I do, however I have my eye on an old iMac Core 2 duo, 3GB ram, 2.13GHZ just as a second machine and for the kids really as they use macs at school, they can be bought for around £150 these days so cheap as chips really. Just wondering how reliable these old macs would be? If It serves me a couple of years I'd be happy enough.
