In my opinion it's like all other gadgets ... only some of them  
deliver an added value. SSD-Disks deliver some really good values:

- shock resistance
- power consumption
- speed

the first two values are important for mobile devices - speed is a  
nice sideeffect.

But have in mind, that all ssd's have a limited lifetime - especially  
multilevelcell SSD's.

If you use multiboot environments keep in mind to optimise your OS for  
using SSD's. Windows 7 with ntfs use trim-function implemented in  
newer SSD-Controllers like the Indilinx Barefoot-Controller for  
wear-leveling the cells.
OpenSolaris with ZFS uses copy on write and distribute the  
block-writings. But it don't balance the blockwritings on the whole  
disk like the trim-function does.
I know that trimming the cells has negative aspects (speed, queueing,  
overhead) but it improve the lifetime of the ssd-disk (multilevelcells  
= 10'000 singlelevelcells = 100'000 writes) by eliminating 'hot spots'  
on disk.

An interesting Thread about this:

So digg first for the ssd-technology before buying...

Kind regards
