Think of a wonderful party with delicious food, sparkling conversation and all your favorite people in attendance. There’s great momentary pleasure and—fingers crossed—scant pain involved.

As I mentioned before it had wireless Android Auto which seemed to be uncommon in this price range, and it had pretty nice, smooth animations in its menus which told me the CPU/GPU in it wasn&rsquo;t completely underpowered, or at least the software it was running wasn&rsquo;t super bloated.
