Yep, you can use them in notebooks just fine, the performance boost is even more amazing there obviously as you won't be comparing them to a velociraptor or two but rather one of those horribly slow notebook harddisks.
Power consumption is not a issue, they don't even use 5W.
There is a theory out in the wild though that it will increase power consumption of the cpu (since the rest of the computer will spend less time idle waiting for the hdd), but I don't really think it would matter enough to negate the lower power consumption of the ssd vs hdd since if you get a decent mobile cpu you are looking at below 20W anyway.

Everything seems more response, especially in the legendarily slugish Vista, applications and programs open noticeably faster, browsing files and folders is quicker, the whole operating system experience is improved.
While it's not really possible to test this increased responsiveness, booting off of the SSD just made the whole system feel faster and more responsive. Is £300 a lot to pay for 120GB? Certainly, but you get a lot more than faster boot and game loads for your money.

Dont think the onboard RAID is limited to 300MB/s, each disk is effectively limited to that but not the RAID controller...
In this youtube vid (2*60GB RAIDed) http://www.youtube.com/watch?v=go8vnZj2vb4&feature=related the guy/gal is using an ASUS P6T WS Revolution onboard raid with to get an average read speed of 417.0MB/s
to sequential read speed across the drive

The problem is that of data pages. Every time you want to change even 1 bit you have to read the page that bit is stored in, erase that page and then write it back. At first, when the disk is fresh and unused data can simply be written to the disk. However, as more and more of the disk's space gets filled you'll have to perform the routine mentioned above. A way to alleviate the problem a bit is to have a huge DRAM cache on the disk. Intel's X25 series has 16MB on-board and I believe the Vertex has 64MB, which is the main, if not the only, reason it's faster than the X25 at writing.
Oh, and by the way, any SSD using the JMicron JMF602 controller is a pure hands-off product. Avoid at all cost! They'll never run fast, even if a "new" design is advertised. They also consume way too much power.

http://www.anandtech.com/storage/showdoc.aspx?i=3531&p=10 (i recommend reading all pages press the print button, but do not go full screen keep it about 6in wide so its more readable) page 10 explanes then TRIM command it alows it to wipe an block so its ready to receve data and for the most part all SSD companys need to do is bring an update out for the SSD

I honestly dont see the attraction to these drives (other then no moving parts). Being a solid memory architecture, does not the memory integrity start to get compromised over use? (something like 250k read/writes starts to get corrupt?)
I would throw the rating down to a 2/10 for value, as nearly $3 a GB is simply to much, no matter how they try to "spin it".
