Couldn't tell it from new.

I really couldn't tell it from new, but the OS is not activated nor will it activate. This is a small problem because without activating the current OS you can not upgrade to Windows 10. The first thing you need to do is to register the Surface to your Microsoft Account. Then, you can download a recovery image from MS to a USB. Tell the Surface to boot from USB and it will install the original OS (activated). You can then upgrade without a problem to Windows 10. When registering my purchase, I did find out that the Surface I got still has hardware warranty with MS until March, 2017. I was very happy about that. The only thing I haven't done is install the LTE card yet. I'll update this if anything negative happens. Summary: Very happy with the Surface. If anything, mine exceeded the description as far as cosmetic blemishes. Edit:06/29/16 I am having issues with the LTE SIM. It's acting like it isn't GSM unlocked. Still trying to figure this out.Read full review
