Value??
I'm not sure how £180 can be considered 'good value for money' when it's up against (larger!) hard drives costing £30 a piece. SSD can't compete in the value range because the technology is prohibitively expensive - even to try out experimentally would just be a waste of money at the moment.
From what I've seen on benchmarks the claimed speed boost just isn't there in real world use - the lack of seek time is offset by the slower read (and *much* slower write) times.
