I'm planning on buying 2 units. One for myself for the purposes of learning web development, and one for my sister for entertainment purposes.
I know that the latest iteration of the device will enable me to use Chromium, node.js, Google's Polymer kit, GIMP, and even a build of Visual Studio Code, which I need to learn how to develop web apps.
As for my sister, she would like to use our dumb tv as a screen for playing Just Dance Now, an online game that is quite resource intensive (plays an HD video while showing real time scores accumulated from different devices). She would like to watch HD YouTube videos as well.
On paper, the Raspberry Pi 3 looks capable enough of handling all of these tasks without hiccups, but is that really the case? I think we may be better off buying a PC and/or a Chromecast for our needs, but we don't have the budget to buy those. We're not wanting or expecting cutting edge performance; we just need the Pi to get the job done, with few issues.
Edit: Trying to get your insights. Should I go for it, or save some money to buy a different device that will be capable enough to meet our demands?
