I don't know what you are on, but the previous Z series, which only benefit it had over the new one is the built in hard drive. That sold for $2,000+ i think it maybe was online for $1600 or so brand new.
I doubt the price will be halved in a few months. The reason the F series was halved was because of the lack of sales due to the known boot up time, lack of responsiveness, and the fact that they were phasing these units out a good 6-7 months ago. I knew about the new units back then. Why do you think I didn't get the 90BT?
