I stand corrected re my earlier comment re HDMI ports.
Looks like the Model A has = compared to the Model B : (a) lower price. (b) One USB port driven directly by the SoC instead of two. (c) lower power consumption - 300mA instead of 700mA (d) No Ethernet port (e) No USB hub (f) 256MB RAM instead of 512MB.
It will be interesting to see how low you can get the power consumption on the Model A. It uses a linear 3.3V regulator which wastes a lot of energy as heat so replacing that with a very efficient switch-mode regulator should cut the power consumption down closer to 200mA.
The new 2013-02-09 version of Raspbian - on the website for download - appears to speed up X for apps quite a bit. Still not going to set any performance records, I think the CPU on the pi is roughly equiv to a Pentium II.
