Best laptop I've had out of 5 of them in 18 years! I've had 3 other Dells that were OK but this one beats them.I'm upgrading the RAM to 16 GB so I can run a virtualization app to run Win7Pro on my Kodachi Linux OS!Windows 10 Pro crashed itself, auto upgrading the video card app, 4 times in a week and a half. So I dropped Windows 10 after the 4th. Reinstall, and went to Linux. Dell nor this seller would provide a Dell 7 Pro, even tho this E7270 shipped new with 7 Pro, and I don't need or want any Windows warranty, anyway!I had Windows Updates Shut off as "administrater's" account, but that didn't stop their "intrusive" updates, even when the video was the latest driver on Intel's site!They blacked screened me all 4 "needless" updates!Using 7 Pro on a virtual box, is the only way I can "test" apps and programs for reviews.
