Hello! I'm going to buy Air 13 inch 2012. Conf: i5, 8 GB RAM, 128 SSD. This will be my main machine for work. Priorities: VM with programming, Internet, music, some games in that order. And: -This laptop is very thin. Are there problems with fans/heating? Maybe programming with VM is not problematic processes for CPU, but... -Will I be able to play some older games, like AC2 or MW3? Not in highest settings, but in good options. But this is only addition, not main task for this laptop. -In what can I cover laptop? Some case, cover? -Will this laptop be good for at least 4 years for these tasks? -Owners of this Air, are you happy?
