Damn Apple..a fence sitter's dilemma

Almost ready to make the'move'...Buy the Mac mini, go with a firewire dac (seems to make more sense to my computer illiterate brain), decided on a simplified Raid backup, still worrying over format to rip cd's....And now Apple introduces a new connectivity mode : Thunderbolt. A zillion times faster than USB 2 and Firewire 800, single connectivity with audio, video, data, etc., and a whole lot of other things I don't understand.
Sure, it's only in the MBP's introduced this week, not the Mini; but trickle down is their modus operondi. Sure, I should get off the fence and make a move 'cause there will always be the next great thing coming down the pipe, but I sure hate to spend my pennies and be obsolete in 16 months. Whaddya' think?
