Sony just added a new TZ ultraportable to their web site, 48 GB is now the max SSD. I don't think it was there yesterday when I was drooling over the 32 GB model.

But it costs an extra $400 over the extra cost of the 32 GB. Also, I read that the 32 GB model only has 20 GB free after a fresh installation.
On the TZ, the SSD cuts the weight from 2.7 lb to 2.6 lb. Size is pretty much irrelevant because the case has to be big enough to hold an HDD in the event you ever want to swap.
PC World did real world benchmarks, and the extra battery life is minimal. Testing 3 different laptops they got a maximum of 9 extra minutes and a minimum of 3 minutes.

And then there is this:
First, he said, the performance and power advantages of SSDs have been overstated. NAND flash, he said, actually is slower in many write functions, and the power saving is only about 5 percent of the total power cost of running a laptop. "A laptops's power consumption for storage is only a small part of its total power needs," he pointed out.
