Thank you for the post just ordered one. Purchased a 128gb retro pi image from eBay and hope for of the more demanding games work on this as struggle on my Pi2 .
Can't comment about cool things, but the most practical benefit I've found of the Pi is to use it as a PiHole. This basically turns the Pi into a local DNS server, which blocks undesired web traffic, while accelerating desired traffic. You get faster web browsing, with ads, tracking, malware, and various unwanted service providers all blocked. It does take a bit of work to get it running optimally, but it's worth it. Looking at the info panel on mine, it's currently blocking 60% of DNS requests, with no loss of desired functionality.
Wow like Mario or contra.. Pretty good
You know you can use this for retro games, media streaming and other things right? :D
U got that right, you can do so many amzing things, one of my fav is controlling electric blinds
