At $50 for a dual-core A9 computer with typically 720p to 1080p HDMI out, 1GB RAM, 8GB Flash, a SD slot, 2 to 3 USB ports, Wifi N, Bluetooth, and nothing else, the poetically named MK808B, MK802III, Neo G4, UG007 and their numerous ICS-running, PlayStore-equipped brethren have enough chops for basic Internet stuff, dlna/LAN/Airplay streaming, Skype, light Office work and light gaming and emulators. Basically, tablets in desktop's clothing.
While not having a touchscreen nor gyroscope nor accelerometer throws off quite a few games (the portrait aspect ratio doesn't help, either), almost all non-game software runs fine, as do about half the games. Surprisingly, Android has OK keyboard and mouse support (no right-click, tough), and most devices also support xbox and DualShock controllers, though few games actually take advantage of that.
No major OEM has launched a product yet, so a few small manufacturers (Minix, Rikomagic, Tronsmart...) are making a name for themselves. Upcoming quadcore, 2GB RAM refreshes with Android 4.2 might further boost interest.
