I was lucky enough to get my tf300 back in september as my first tablet for $170 on cowboom (originally was going to get a tf101 but couldn't pass that up, also even though I bought it used it came in pristine condition), so for that price I might be a little less critical than others on the tablet, but from then until now it's been working like a dream. I mostly use it just for simple things like movies/web browsing/reading/video games and the like, running cleanrom since september (currently on 3.4.4), with really no complaints at all.
There's been small instances of it seeming to lag a bit/not performing as well as usual, but more often than not that's been remedied through rom updates, kernels, and certain apps. I'd definitely recommend it if you want a 10 inch tablet and can find it for $250 and under, if you're spending more there might now be better options since I bought mine or tablets coming out in the near future worth waiting for. Also, I was real happy that this came with a slot for a microsd card and an hdmi cable because it seemed hard to find both on a decent tablet around the price range.
It's a big bonus that the community for the tf300 here on xda is so helpful. I've been rooted with the bootloader unlocked since day one, which is something I know others are hesitant towards doing, but it was easy enough doing it through here without any problems, thankfully, and I've learned a lot going through these forums. With all of that to consider I definitely don't regret picking up the tf300.
