Cool. I can't wait until this fall when it's time to update my company laptop. My current Dell Precision M6600 was about twice that when I got it two and a half years ago. I think the upgrade to the Nvidia Quadro 3000M w 2GB of RAM was about $800 of it.
The CPU is only a tenth of a GHz faster on this model than the one I currently have, and I have 20 GB of faster RAM along with a 256GB Samsung 840 Pro and a 750 GB spinning disk. 1080X1920 was the highest resolution I could get at the time, but I think the built in screen is 17". The higher resolution would be a really nice improvement.
The newer one weighs less than half of the one I have now. But I'd be curious what the weight of the power transformer is. On my current system it is about the size of a clay brick and probably weighs close to 2 lbs. I can get about 2 hours out of the battery with no real power reduction crippling the system. Probably 3.5 to 4 under the most favorable conditions. So 9 hours would be a big improvement too.
I'll have to wait to see if Windows 10 is worth bothering with though. I suppose I could always install Windows 7 from the recovery disks that came with my current system.
