Even more on Chromecasting.

So after playing around a bit with Chromecast, here are some additional notes:

• Since you can cast any Chrome browser tab and because you can drag and drop supported media file types into Chrome browser and have them play / show up, you can also stream to your TV:
• local MP3 and certain other audio formats, though not .OGG and .FLAC.  Of course you don't really need to worry about this when you have your music online in Google Play Music.
• images (supported file types, only, of course).
• Speaking of images, you can also cast that tab with Flickr, Dropbox, etc. and look at a curated folder of images.  I'm thinking it'd make for awesomely large presentations.
• You can also, therefore, stare at your digital magazines, viewed within Chrome on your computer, on your TV screen, with some caveats (below).
• When you stream music via Google Play app, it moves the title / progress bar and any cover art around the TV screen so as to not burn in any images; the same goes for the Chromecast home screen as it waits for you to cast something to your TV.

There are some improvements needed, however:

• As I've previously mentioned, drag-and-drop video content results in a tiny lag between audio and video, of about 1/2 a second -- something that should be correctable with firmware updates -- but it's not that bad.  It's an ever-moving target as sometimes there is zero lag and other times it's a half-second delay that looks funny.
• Text rendering is terrible, so casting a Chrome browser tab is not very useful if the intention in blowing up the size of a web page / digital magazine is to read the text.
• Sometimes you can't play one music file, then skip over to another music file within the Google Play Music in Android, without having some hiccups along the way.  The easiest way to resolve this is to disconnect and reconnect to Chromecast.  Of course if you stream just playlists, you'll never run into this issue.
• Curiously, you might not see the Chromecast button in your Android apps, until after you've opened and closed them at least once.  I've noticed this in the Music and YouTube apps.
• I'd really like to be able to cast from within the Google Play Books and Magazine apps (and have text rendered properly), because then I'd be able to have a reference book open on the TV while I worked on my laptop.

I plan on putting off activating my free Netflix streaming codes until late-September / early-October: My DVD queue jumped up to above 40 discs, with another 12 saved videos about to be released, and the plan was to eventually move to 1-disc-at-a-time while adding streaming after I had gotten down to about 10 DVDs.  Almost there.

All in all, an extremely awesome device for $35, and because it's Google and the platform is open with an SDK, it'll only get better.  This is going to be awesome!
