SSD's aren't worth it yet in my opinion. They are way overpriced. The only place I would consider using one is in a laptop that is constantly subjected to movements, shaking, etc. as hard drives are extremely sensitive to movement. Also, new hard drives are really quiet, my new Seagate 1.5TB is nearly silent while my old 60GB Maxtor makes a loud whirring noise. SSD's will cut out the sound completely, but with a quiet hard drive you'll still only notice fan noise.
