Hi Guys, I am near the point of changing from PC to Apple - probably MacBook Pro. I would be interested to know : 1. How long roughly did you keep your laptop before replacing it, and whether you got a couple of years 'extra life' out of it by adding RAM, increasing HD size or anything else. 2. Did you get it to use for one or two specific needs (e.g. Video) - or did you get it to use a 'general purpose' computer? Did that actually work out, or did you change your main use? Thanks in advance for any replies!
