Why Apple TV does not sell well?

First, I love Apple TV. Because of it, I have been able to listen to music more often, entertain guests with funny youtube videos, and see long forgotten photo albums. However, for the all good things Apple TV does, there are so many others that it doesn't do so well, which probably explains why the product didn't take off in the market.

1. Apple TV has only supports HDMI and Component Video ports for connecting to TV; older TVs have neither of them. Just by that, the market reach of the AppleTV reduces substantially. 

2. Oversimplistic remote. Apple is known for cool and functional designs. However, AppleTV remote is way too simple. Desired options: a) control volume, b) TV option to choose HDMI port to use (currently, first I have to use TV remote to first switch input to AppleTV HDMI port and then use AppleTV remote). c) one-button-play (as the name suggests, with the press of one button I'd like to listen to music on AppleTV)
