No, if you use a lot of programs for different reasons (or heck, just like to install and forget about it) SSDs do not apply to you. The cost is currently too high.
Anyone who says that has never used an SSD.
Seagate Barracuda 500 GB HDD SATA 6 Gb/s is currently about 40 bucks
SAMSUNG 840 Series MZ-7TD500BW 2.5" 500GB on ebay is 380 bucks
Cannot be justified.
