Till they get cheaper and more reliable, ill stick to the regular hard drives.
I would also stick with my spinners!! Atleast for me its too steep a price.
What I've been considering lately, as an alternative to SATA-based SSDs (which are really HD replacements) is the variety of SSDs that fit into one of those odd little PCI-e slots on your motherboard. Those are generally only used for high-end sound cards, but a number of companies (including OCZ) make memory cards for them.
They all seem to be PATA-based, but I'm thinking that if they have a better read rate than a SATA drive (due to hooking into the PCI bus instead of going through the disk controller) it might be worth it. Especially if you're stuck on one game with a disk-load bottleneck (cough cough World of Warcraft cough).
A 16 GB card can be had for $50 ($91 for a 32), making it more expensive per GB but less expensive if that's all you need.
