I really get the sense that Thunderbolt is another Firewire. Very seldom used, high cost due to the circuitry needed.

Just curious but those of you who have Thunderbolt on your MBP's would you rather those would have been extra USB 3.0 ports instead?

It is not another FireWire. FireWire was quite popular and not that expensive.

I'm so used to Thunderbolt,SSD's and USB 3.0 I don't know what I'd do if I had to go back to slower technology.

Albeit for an expensive price. Well worth it imho.

I wonder if this affects Thunderbolt -> HDMI adapters in any way. :confused:

No. Such adapters are really Mini DisplayPort to HDMI adapters, Thunderbolt isn't involved.
