I purchased one of these on August 23, 2019 for $500 from a weird online retailer that had decent service. After tax it was about $550, then I bought an extra 8GB ram stick for $40 on Amazon. I also saw the E495 on Ebay for similar prices. Taking it apart was easy, and Lenovo provided good instructions for that process. I ran pcmark before and after installing the extra ram, and adding it did make a 20% difference in graphics performance. It's crazy that Lenovo ships these things with single channel ram by default when the chip requires dual-channel ram for good graphics performance. The NVME SSD is very quick, even on the 256GB model, and is the fastest part of the system (and highest rated part on PCMark).
If you're using this for games, you're crazy. But I've found it excellent for regular office work, internet browsing, streaming, and the like. The battery gives me 4-8 hours of life in normal use, which is better than I expected. The screen is decent quality but dark. If you're going to use in direct light, you'll have trouble seeing the screen. The bezel is big. The chassis is fine- not as good as the T series, but better than most options at the price point. It's not too heavy to carry around, but borderline. My biggest complaint is the wasted space- the bezel, and inside the chassis, where there's space for a 2.5" drive despite the M.2 default connector. They could have made this thing a lot smaller, and lighter, without increasing cost. They're trying to differentiate from the higher-end machines, which I didn't want to pay for, so it's up to you to decide if you want to spend extra for smaller form-factor.
I'm dual booting Mint 19.4 without problems. A couple missing drivers, but otherwise good. I had to upgrade to the 5.x kernel to unlock the GPU (and stop the annoying startup "no hardware graphics acceleration detected" warning. I've tried dual-booting on Dell XPS laptops and encountered a world of BIOS pain, so I'm glad it was so easy here.
So what do you want? It's not sexy, but cheap, effective, has lots of ports, easily upgradeable, and works great. Even a budget Thinkpad is better built than the price-equivalent Asus or Acer machine.
