Surface Pro 4 with Microsoft dock. This this has surprised me how well it can play some games for how weak it is. Enjoying a lot of indie games and some AAA games on low settings. Plus handles all emulation fine so retro gaming is great. It's portable to take with you and use a controller if you have a bag. Battery is pretty bad when I game (2 hours). But when I get home, I just slide it into the dock and I can play the games on my TV.
$1000 solution for a semi switch gaming system (portable/console/pc) hybrid.
