Personally I wasn't willing to wait the quoted 4-6 weeks for an iMac with a fitted SSD, especially as they can stick anything they can grab their hands on in there and be done with it.
I'm pretty sure thunderbolt SSD's will be streaming onto the market in a few months and once the cost is sensible I'll pull the trigger on one.
Same here.
But Can you be sure you can boot from a TB SSD ??
I think this gives pretty hard numbers (110 orders tracked so far, 1 having shipped). Statistics tab gives a pretty decent breakdown:
2011 Thunderbolt iMac w/ SSD Shipment Tracker
I think there's a very high percentage of people who want an SSD, but not from Apple for $500-600. I suspect they're voting in both categories, rendering this poll near useless.
I interpreted it as 'ordering with SSD' and voted no, although having used SSDs in both my systems for 2 years, I'll definitely have one in my iMac, but not BTO.
