Lots of people love the Lenovo X220, which can be upgraded with simple screwdrivers to the latest and greatest processors and motherboards using fan-made motherboards. (That’s how popular they are, fans are making newer motherboards for them. I don’t know the experience, I’m using a very old Toughbook to devel since my needs aren’t great.) What’s with the hinges? I’ve never had one fail. Granted, I’m no road warrior.
I'm surrounded by fancy machines but the X220 just keeps on finding an excuse to be used. I would say I use it more than any other machine. The thing has a soul. I love it. I took > 20,000 photos today from a cessna using it's inbuilt ethernet port and four machine vision cameras. When you're paying for aircraft time and are bumping around a bit, having that thing on your lap makes you feel like you have a good wing…
That sounds like a cool project. What was the goal?
