Maybe he deleted the source for Vista along with ME. 

I sport a HP NC8430 2.4 Intel Dual Core with 4GB Ram, Macbook Unibody 2.4 with 4 GB Ram + 7200 RPM 500 GB Drive, and a HP TouchSmart tx2 with AMD Turion x2 64 with 4 GB Ram (Multi-touch) woot.  I have a broken back by the way due to carrying all three in my backpack on occassion.  I need a new one that supports 8 GB now.
