Wild blueberries. I love frozen fruit in general (like a healthier version of popsicles), and wild blueberries are my favorite. They're smaller and way more flavorful than normal blueberries.
The G series do not include any stand. They are only intended to be wall mounted. You can buy a center stand that is identical to the C series if you want to though.
The local transfer compresses it with the same format the CDN would use, so if the local PC turns off, it just continues via Valve's servers. The downside is that the compression is quite aggressive. My PC with a 5950X can only go like 300Mbps on local transfer, so the CDN ends up being faster for me since I have gigabit internet and the Deck can get 600 Mbps even over WiFi.
For people with slow Internet speeds, it's obviously a great feature though.
Not really. I've never seen .cache get bigger than 10GB, which is about how big the temporary files in Windows get if you never clean them.
