Too much, is the probable, and true (and yes, unwise, but it's my choice to spend my disposal income as I choose) answer.........
Actually, the other side of that coin is that I don't mind waiting; I don't doubt, that in the long run, or even the medium term, the price of SSD will come down.
Good grief, I can remember a friend in a cutting edge applied linguistics department (i.e. a pretty tech savvy lot with an interest in cutting-edge technological innovation) in my country's top university campus in the mid 1990s, showing me, in an awed tone, the first 1GB monitor possessed by the humanities sector. I have to admit I was suitably impressed - in those days, I owned a desktop computer with a HD memory of 80MB.......
Tempus fugit.....
