Laptop hdd or ssd?

So I just ordered an x200 lenovo thinkpad. It comes with a 5400 rpm hdd. I'm assuming hitachi.

I plan on using the notebook for networking, learning virtual machines, linux, etc as well as going on the internet and word processing, things like that if I am studying somewhere when I'm not near my desktop.

I also plan on using win 7 pro since I only had to pay $30 for the license and I want to do networking stuff with it as well.

I don't know honestly what is the best drive to get. I want performance, but can I justify the cost of a ssd? I do own 2 SSDs right now, so I know the benefit (both ocz agility 30gig and 120gig).

I don't mind spending $240 or so on a drive, but if in reality I do not get very much performance, I'd rather have the space to dump music and run multiple OS's with a lot of room for partitions.
