The new MacBook Air was introduced at MacWorld with the option for a 64GB Solid-State hard drive. Toshiba is also now offering Solid-State drives in sizes that are 32GB, 64GB and 128GB. The drives still seem to be lagging in adoption due to high costs, but they offer more durability, faster boot times and lower power requirements which should all lead to higher adoption over the next two years.
Toshiba will also begin making Solid-state SATA drives in May that can be used in desktop systems.
