So if you’re looking for a computer that you can not only take with you wherever you go, but that’s so compact it’s not much bigger than a USB flash drive. Then This Linux-based device that runs Android 4.0 may be what you’re looking for. Available online for $74 this 3.5″ long device packs in an AllWinner A10 single-core 1.5Ghz ARM CPU, a Mali 400 GPU and 512 of RAM. Connect this to any monitor that has a HDMI port to display in 1080p and is also capable of HD video playback. If you notice the small port next the USB port it would seem that it requires a power supply and does not power from the USB.
This device also comes a full-sized USB port (USB 2.0) with host input support, a Micro USB port, a Micro SD slot, an internal 802.11b/g WiFi antenna and it can even boot form a micro SD card running Android 4. or any another ARM-compatible Linux platforms. You will also find a HDMI port to connect to the display of your choice but keep in mind you will also need a HDMI cable to do so.
If you would like to purchase and see more specs check out Aliexpress. For now you will need to pre-order as they are sold out but more are expected around June 10th.

I just covered this earlier today too. I’ll definitely be testing one of those out, considering it’s only 74 bucks!
Its really affordable for what you get. I thought you might be interested in this.
