Intel came out with lightpeak and the new macbook pro's have thunderbolt ports.  It is 10gbps.  How fast is this?  How long would it take to transfer a 500 MB file? or a 1 GB file?

10gbps = 10240MBps (or 1.25GB), so theoretically you could transfer 1.25GB per second with the technology, but all of the other components would have to be able to write this fast. For instance, new SATA drives can supposedly write at 6Gbps, so in this instance, you would have a bottle neck at the hard drive. In other words, the fastest the file could transfer even with Lightpeak technology is 6gbps because that is the slowest point in the transfer. Lightpeak will be utilized better in the future and will be able to quickly transfer data to and from RAM and the CPU, but right now the hard drives are a slow point. Hope this helps.

It does.  So if I had a 2 macbook pros with the thunderbolt ports and I wanted to transfer a 10GB file would this just take seconds?

Theoretically yes, but those are simply the specs and not necessarily real world numbers. It's like when the DSL company tells you that you get 10mbps, you never quite do. You get about 80% of that, but yeah it should be pretty fast if you were doing large video/audio files etc. Again watch out for your bottlenecks though.
