I have had a Momentus XT in my work laptop for a rather long time now, had it just about since they where first released.
I purchased the system. However since I was in store they tweaked some prices to sale prices and I was able to go with the 2500 i5 for about $7 price difference.
Been assembling for but had to take a break for the kids bed time. Also picked up a new 23 inch monitor. All in it was still under a grand even with the extra taxes.
