While it's great that the new iMac has Thunderbolt, it's really not that important right now. The reason is that there are not any devices in the market that support it. Will Thunderbolt be the next USB? Maybe. But until people actually make stuff for it, I'd advise against purchasing a new iMac based solely on that feature.(Disclaimer: I have a Thunderbolt MBP, but I bought it because my 6 year old laptop couldn't go more than a few hours without crashing.)
