I almost bought a Yoga with 16GB ram and a very fast AMD processor on black friday sale at bestbuy for $500 a couple years ago. A friend talked me out of it because the 16GB ram was soldered in and not expandable. Similar machine is around $1000 now. Yeah get something sort of recent. Depending what you’re doing 16GB ram is more than plenty. 8GB is ok, 4GB is marginal. My 2011(?)-vintage T510 is ok for most of my purposes, but youtube has been migrating to cpu-hungry codecs so videos these days bog down the cpu and look janky. Maybe I can change some settings to fix that. I do like the idea of a yoga-style tablet for use as an e-reader.
