The competition is not sleeping as a company called MeeGo is already selling a similar device for €98.16 or $109.99 for US customers, significantly less than Intel's Compute Stick.
The MeeGoPad T01 is one of a handful of HDMI dongle sticks powered by Intel's Atom Z3735F that runs Microsoft Windows 8.1. The company calls it a TV stick and the 64-bit Bay Trail-T with four cores, 2GB RAM and 32GB of internal storage is enough to run Microsoft's current desktop OS. The CPU has a 2W SDP and top speed of 1.3GHz. It is a 22nm part with 2MB of cache.
In case you need more connectivity, the HDMI stick comes with 802.11 b/g/n, Bluetooth 4.0 and a microSD card reader with support for up to 64GB cards. There is even a proper USB 2.0 port on this tiny stick, as well as a power button and a micro-USB port to provide the power.
The only thing we don’t really like is that the dongle comes with a trial version of Windows 8.1 and the company doesn’t specify how long the trial is good for. In case you wonder how big this stick is, it measures 99x37x9mm (L x W x D) and weighs 44 grams. Chromecast is slightly shorter but thicker with 72 × 35 × 12mm but weighs 34g or 10g less than this Windows TV stick.
You will need to power the MeeGoPad T01 TV stick with an external USB power, as HDMI wont let you use any power, but at less than €100 this stick definitely sounds interesting.
