Looking up disadvantages in the above linked article will underline why I think SSD will not be found in mainstream computing for a good while. Flash memory is good for a finite number of reads/writes. When using a SSD for windows with the swap file on the drive it hits the drive quite often and each hit is a nail in the coffin for the drive.
To help extend the life of the drive you can transfer the swap file to a conventional disk type HDD and save thousands of read/write cycles to the SSD.
