I'm likely buying one because:
1) want to stay on OSX
2) don't want to support a hackintosh
3) want to get something that will last another 5+ years
Caveat here... I'm on a stock 1,1 oMP right now, and I don't feel that spending $1k to upgrade it to have a 2,1 is really a great investment now. If I had a 4,1 instead, I might upgrade my existing hardware instead.
Personally, from all i've seen here, I think that the 3,1 systems might be the break point between upgrading an old system or ditching it and getting a new one (assuming you haven't been doing upgrades to your hardware along the way).
