I have also heard mixed reports on the actual speed, power and heat topic. I have heard though that the intel ssd is insanely fast (supposed to be faster than a wd 10,000 rpm wd velociraptor) but it cost way more than a normal ssd and I believe the max size is 80 gb and it cost around $621 american dollars.
The only true advantage right now would be that they are completely silent and they do not vibrate the notebook.
Personally I would suggest that you use a normal hdd and then in a year or two when they become cheaper and all around better, then you could upgrade.
I hope that helps.
