I'll grant you that SSDs are much better in certain respects. What makes them not worth it at this point though is what you failed to address: price. Just look at this picture:

Until SSDs become more widely adopted and the prices drop, there's almost no justifying buying one over an HDD for anyone who doesn't really, really need it.
For a MBA, you currently get a choice of 2 models. The SSD version is a $300 premium. For this you get:
1) 2.13 vs 1.86 processor
2) 128 GB vs 120 GB drive
3) Longer battery life for any disk intensive applications
4) Less noise
5) Much better shock/vibration immunity
6) MUCH faster performance (loading aps, booting, etc)
For me... spending the extra $300 is a no-brainer... primarily for item #6. I am not saying that this would be true for everyone... but the OP did state that price was not an issue.
