The picture shows that it's quite small and also that it contains Windows 8.1. Isn't that amazing? The CPU is a quad-core Intel Atom. The Windows version of the device has 2GB RAM and 32 GB persistent storage. There's a Linux (Ubuntu) version and it has 1 GB RAM and 8GB persistent storage.
What this means is that you can turn your large screen TV into a Windows PC by connecting a 170$ stick to it and of course a wireless keyboard and mouse. The Compute Stick comes with USB, WiFi, Bluetooth, a micro-SD slot and an on/off button. That'll give you a PC with a huge screen. I don't think it's good enough for serious gaming, but sufficiently powerful for most other things, including Youtube watching. Through the WiFi and a browser you'll have access to your Google Docs of course, so what more do you need.
Most PC monitors now have HDMI too, so even if you're not a TV-fan you might still have a suitable screen for the Intel Compute Stick.
