I use it every day, its absolutely reliable, its a real workhorse, its on all the time I am, from doing my Uni work in Logic, Sibelius etc, to planning my lessons through ical. To editing photos with photoshop, uploading them straight from iphoto to facebook. Using time machine to drag back files i tinker with. My Macbooks perfect. Just wanted to balance out some of this apple bashing thats going on.
