SSD's are not the way to go unless you have very specific situation you want to solve (say, fast boot up time).
The reason is simple:
A 2.5" hard disc use 1.7 watt power while a 64 GB or 128 GB SSD uses 5.7 watt of power...that is more than 3 tiuems the requirement of a normal notebook harddisc...and, you get much less space.
The 32 GB SSD's use 1.7 watt of power too so there the power usage is the same. But, since you wanted more space than that then a 2.5" can today hold 640 GB in 9.5 mm (2 -platter) from WDC or Toshiba.
Another issue with SSds is that they use more pwoer ALL the time when watching a movie. A SSD does not have "idle" currently so it will use 5.7 watt ALL the time if you are watching a movie - while a 2.5" normal hard disc goes down to 0.3 watt when idle...
SSD is really only good if you have very specific needs - in 5 years it has improved greatly, yes, but today it is more for a small part of teh market.
