The Giada Q11 has some rather interesting features, like its many I/O ports, the ability to take an internal 2.5" HDD or SSD, its extremely low power consumption, an integrated audio amplifier, built-in WiFi and Bluetooth, and, on top of that, support for many different display types. It also easily played back every multimedia file we tossed its way, even the ultra-high bit rate ones, and has access to the Google Play store, so you can download and install thousands of applications, but not all of them are compatible with its hardware and the display mode (landscape) it supports.
Its most notable negative aspects are the weak CPU and low amount of usable RAM. Both significantly limit its usability in many areas and set the bar lower than expected; even today's mainstream smartphones are equipped with much stronger processors. You can also easily find a quad-core mini PC with 2 GB of RAM at a lower price than the Q11 in various, albeit Chinese, stores. The latter systems may not have as many I/O ports as the Q11, or its construction quality, but their hardware is way more capable, which dramatically increases their usability. The Q11's weak CPU greatly restricts its capabilities, which is a great shame as it is an interesting concept. Also, the lack of detailed documentation, the low quality and hard-to-use remote control, and the lack of a proper interface that would render the vanilla Android environment more user friendly just make things harder on the end user.

To conclude, I think the Q11 would be much better with a stronger CPU, more RAM, and a Wii-like remote control. All of those improvements would also fully justify its mini-PC description. It is unfortunately only good for digital signage purposes or as a mainstream media-player device that can reproduce any type of file, regardless of its bit rate. The strong advantages of the Q11 are its good construction quality and the fact that it carries a ton of ports and interfaces, making it ideal for business purposes where computational power plays a secondary role. Also, the Android OS it runs naturally gives you access to numerous applications, so you will easily find the ones best suited to its hardware specifications. That said, the Q11 simply isn't for your if you are looking for an HTPC replacement.
