I run multiple vitual machines but mostly linux installs and a single win7. Have settled into approx 90GB spare on my 256GB so I think this will do for the moment.
I have a lot of my archive files on my home network drives so that saves a lot and I think with a little housekeeping and categorising of your data you will keep the usage of your 256GB down.
However, having said that I do note that OWC have been tinkering with upgrading the SSD drives so that may become an option in the future if you want to upgrade the SSD yourself - I will definitely be keeping an eye:
