maybe get a nexus 2013 for cheap? I'd agree not to spend $500 on an android (aka samsung) tablet...
maybe some chinese shit off off geekbuying or something? there are some pretty decent tablets for $2-300 there... (even dual booting win10 and android...)
asus z170-A || core i5-6600K || geforce gtx 970 4gb || 16gb ddr4 ram || win10 || 1080p led samsung 27"
