OS X? Great, would never put up with windows again. Mac hardware? Looks cool, and it's aluminum. I ordered 4 Macbook Pros last July-August and this is my damage report: #1 - (user error) damaged by liquid spill. took 3 weeks to get parts. #2 - (defective) screen went bad. took 3 weeks to get parts. #3 - (defective) keyboard and trackpad are bad. it has been "repaired" twice. #4 - (defective) does not go to sleep when closed. it has been "repaired" twice. I figured with 4 machines and Apple's record, one would be a dud. But they all have had major malfunctions compounded by a lack of parts availability. The parts are also never on hand. I feel like I should switch everybody back to Dell/HP/Lenovo for the next iteration and at least get 24 hour onsite service. This is frustrating. ah - and before anybody asks; all of them have LED screens with no yellowing. so, we dodged that bullet.
