Why would you need 5 Macs? I'm really curious.
1 iMac for home, 1 MBA for myself, 1 MBP for the wife, 1 iMac at work (primary work machine), 1 Mac Mini as a build machine at work,
I'm planning on buying another mini as an HTPC as well :) Now, go ahead and ask me how many iPad's I have lol
As for living alone, you can decide if that's best :)
- MacBook Pro
- iMac at work running OSX
- iMac at work running Win7
- iMac at home
- Mac Mini at home as a server
- Mac Mini at work as a server
Soon we'll have another laptop...
