Boom: I bought Chromecast (updated).

Just half an hour ago, Google introduced Chromecast, and, following the end of their live streaming broadcast, it showed up in the Google Play Store.  So naturally, I bought it on the spot (Order date: Jul 24, 2013 10:30:37 AM PDT); didn't even need to think twice, and here's why:

• Stream your Google Play Music to your HiFi AV wirelessly, using any laptop, iPhone, iPad, Android phones and tablets (yikes, no Windows Phone or Blackberry!) as your remote control.
• Stream Netflix videos (you get 3 free months of free streaming!)
• Stream YouTube videos.
• Steam photos from your browser.
• It's an HDMI dongle, powered via USB...no confusion on cords.

The way I see it, Chromecast is better than what the Nexus Q was supposed to be, and for a substantially lower price than the Q.  I couldn't resist, and jumped on it.

Update: Google's promo of 3 free months of streaming Netflix ended quickly. Apparently the Chromecast device is so popular, they simply ran out of promo codes. We know this: Google sold at least 250K devices in just one day.

In fact, they're backordered everywhere with shipping now a full month out.  On Amazon, people are reselling their own devices for double the price and up, even as Amazon is out of stock.

This is just crazy at how popular Chromecast is, and obviously Google wasn't prepared for the wave of orders.  At $35, it beats the price of getting a streaming video box.  I'm just glad I got my order in, just a half hour after Chromecast became available.
