Well my 4 year old windows laptop is on it's last legs and after hearing horrible reports of vista I thought I might give apple a go. Got about a grand tops to spend so do I go for an ex display new MacBook pro 15.4" 2.4 ghz in my local computer shop or do I go the eBay route and get an Older 17" MacBook pro with probably a 2.2ghz processor?? would love a new 17" but can't afford it. Also would either of these be up to editng avchd high def movies without too much trouble? plus that's another reason wanting a 17" display!
