[oström]

Hi, I'm about to buy an iMac 21", buuut, I want to be able to use a SSD as my primary hdd as soon as thunderbolt cabinet comes out, the problem I'm having is that I also want a secondary screen connected to the iMac, and tb and display port is the same port =/, will there be "thunderbolt" hubs?

Since TB is able to daisy-chain (like Firewire does), and the enclosure you will get has two TB ports, you can connect the enclosure to the iMac and the external display to the enclosure.
iMac - TB cable - enclosure - MDP cable - display
