So, tomorrow I'll order the 15 inch i5 AG. Questions I have: 1. is AG worth it? Read that AG is more Grainy? 2. How is the resale value of a i5 AG? ( black bezel of glossy is more pretty / people want a used i7 instead of i5 ) 3. No more freezing issues? 4. Is a 15 inch too big in an airplane or in a train? 5. What mouse shall I use, gaming Windows mouse or Apple's magic mouse? I only need the mouse for gaming I think, and I don't think Magic mouse is as accurate as a gaming mouse. 6. What external HD shall I got, timecapulse or a MyBook from western digital ( or other brand? ). I hear alot of stories how those Apple time capsules die after 18 months.
