I agree but what I have noticed from doing some troubleshooting is that applications now-a-days (or rather always) use up more hardware as time goes by. For example, I verified with perfmon that my IDE accessed over 50,000 files when i clicked on 'Open' and the directory tree popped up. It accessed every file in my Documents and other standard folders. Browsers also use up a lot of disk IO. Just by getting an SSD you speed up your web browsing.
