I was a bit skeptical about GoogleTV when I first got it. My main intention was to have a device that could integrate with my TV experience. I have two Rokus, which are actually quite cool, but because I had to change inputs and switch from "TV" to Roku Channels (by switching HDMI Inputs), I used it far less than I hoped I would. I should say that I have Harmony remotes that makes switching back and forth quite easy, yet I still switched to the Roku far less than I thought I would.
That all being said, yes, GTV isn't quite living up to ALL my hopes yet, BUT, I don't think I could go back to NOT having it. Yes, the blocking that the many of the content providers are doing sucks (but not really to me, since Hulu isn't really important to me). DNLA from my Mac to the GTV works just fine, although I don't have much content on my Mac that wish to view on my TV that often.
I needed Netflix, and the web. I can't tell you how many times I hit the Search key to google something someone just said on TV, and boom, there's my search result. I can listen to Pandora, while "watching" a TV show. All my podcasts integrated into a single queue with my bookmarked websites, my DVR'd event's AND my EHD archived recordings is kick-ass.
Oh, and the thought of a keyboard in my living room seemed insane to me (and maybe it actually IS insane) but it has found a permanent home on my coffee table, and doesn't seem so insane any more.
The single input concept is what makes GTV brilliant. The silo'd approach of Roku, Boxee Box, Apple TV etc, being on different inputs is now a non-starter for me. Those companies should definitely be working on the HDMI In/Out overlay approach that GTV uses.
My Nexus One phone is simply the best phone I've ever owned. I've never used a smartphone (and I've had many) as much as I use my Android phone, so I can't wait till GTV gets access to the Android Market. The thought of having all the apps that I have on my phone on my TV is my single biggest technology desire for 2011. I honestly can't think of anything more useful to me from a technology standpoint.
So, ok, yeah, GTV could use some improvements/refinements, and access to everything on the web (ridiculous that content providers can effectively block certain "PCs" from accessing content that other PCs can access, and should be illegal), but I'm now a convert to GTV. Sure Google may have blown the introduction, and GTV may fade away as a result, but many people who diss it because of the reviews it's gotten, may very well be missing out on something quite cool. It has certainly changed the way I watch "TV".
