What planet are you living on? Apart from the Thunderbolt display, there's lots of storage devices available. If you don't want storage but something else, you can get Thunderbolt to PCI expansion boxes that you can plug your favorite card into.
So what's your problem?
The post you downvoted was correct. Saying you are underwhelmed by an improved technology just because it's new and unsupported is just silly.
Why would I want a PCI adapter box? I could've done that with Firewire (400 or 800). I want some native devices.
I haven't seen any other laptops shipping with TB interfaces, either (but I'll confess to not having looked thoroughly.) This is probably what's keeping native devices from being more numerous.
FWIW, Thunderbolt is crap, precisely because it's been almost two years and there's still not a fucking thing to plug into it.
