Hmm, my title may be a bit misleading. I do understand Thunderbolt (I/o, 10 Gb's per sec, etc). However, some people have noticed the Thunderbolt port is the EXACT same as the mini display port. Whaddup with that? Does that mean, my old iMac with a mini display port is different than the coming iMac with a mini-display-port-renamed-thunderbolt? The ports are the same, it looks like they just renamed it.
