I have a 128GB SSD card. Just installed Win7 Pro. Now have about 70GB left. Other programs I use are Microsoft Office, Lightroom 3, Adobe Master Collection and 5 different browsers, as well utility apps. I'm pretty sure I'll max out the size before i finish installing all those programs. I have 3 large HDD also. This must be a common issue at the minute because of the relatively small size of SSDs. What do others do regarding where to install other applications?
