My new MacBook Air arrived Monday, and it runs great. I updated the new computer using the back-up of the old MBA on the Time Capsule. The only disappointments were losing a few PowerPC apps (Spaceward Ho, Galactica, and mac the Ripper). Now the question is what to do with my first-gen MBA. My girlfriend could use it in place of her Dell. Her needs are pretty minimal: surfing, email, and opening Office documents. So my options: 1) Just fire up the old MBA and delete my documents, keeping the same computer name for the wireless network. Question: will the installed copy of iWork still be authorized, given that I installed it from on the new MBA from the Time Capsule back-up? Will my copy of Snow Leopard be authorized? 2) Start from scratch and reformat the old MBA, buying new software as needed. In her case, probably just iWork. Ideas?
