The alternative to the Atari 2600+ is shaping up. It has an SD port and with each update they open up a little more in emulation options. I'm just anticipating the commodore 64 getting included on the list. It has enough power to emulate some 16 bit so maybe early amiga games will run as well. It's a handsome little machine and arguments against it are moot if you were in willing to compromise on other emulation systems like the c64, the Atari 2600+ or the NES classic.
And it has USB ports to add better controllers if you can't adjust to wireless latency. It isn't bad.
