Tony Fadell and his Nest team are now heading hardware at Google, even Glass was moved out from the Google X division into the Nest team, so my thought is that Android @ Home has become a part of that team as well. My cousin did tell me a while back that Google had moved a lot more engineers into the hardware team so I guess we'll have to wait and see what happens at IO.
I'm hoping for a large Nexus Player / Android TV update as well. Right now, every single smart TV product on the market feels like a beta to me, including the Nexus Player. None of them have cracked the market, not Apple, not Amazon, not Roku. Proper Google Photos, Google Drive and Dropbox integration, with adaptive TV interfaces would be a logical move. Google must surely be working on this. Right now, I have 1 terabyte of Google Drive space that just isn't getting used to it's full potential. I really like the Nexus Player, but the experience right now seems limited. I'm not entirely sure if there's a lot of specific things that I WANT it to do, but I want to be shown use cases that I wouldn't even think of myself.
I'm pretty happy with the state of Android Wear, as it stands right now with 5.1.1. I don't have that update yet on my G-Watch, but I've used it on a G-Watch Urbane that my friend who works for LG showed me. Once I get that, I'm happy with Wear. It's leaps and bounds ahead of the software on the Apple Watch. The only thing I find myself wanting now is better hardware and a bigger screen, I'll probably go for a second-gen Moto 360 once that drops.
My Chromebook is still happily cruising. No degradation, no slowdowns, no lag and I've had it for 10 months now. It's really a perfect portable web machine, and I only paid £180 for it. Since I bought it, there's now 5 more people in my family who own Chromebooks in different models. Like I said, Apple and Microsoft ought to be worried about this.
