Nexus Tablet
While the Nexus Tablet has a very powerful chipset with a quad-core processor and impressive graphics most are not comparing it to the iPad, but instead comparing it to the Kindle Fire (this has to be a disappointment to Google). Partially I'd agree, the 7" form factor is ideal for reading, though it's also ideal for small hands, so kids would love this platform, add to it the price of $199, if it gets broken it's not the end of the world.
Nexus Q
The Nexus Q is a brilliant concept, though it'll be interesting to see if it leads to any divorces or shouting matches between kids or roommates. The Q is called the first social entertainment hub, essentially what the Q does is stream content from your Google Play cloud to the device and then broadcast that via your entertainment system (speakers/TV). How it connects to your device and Google Play cloud is interesting. If your android phone has an NFC chip in it, you simply tap the Q with your phone and this pairs your phone via bluetooth to the Q, you can then control the Q's playlist via your phone. What's interesting though is let's say a friend comes to visit and wants to add something to the Q's playlist from their phone, they can also tap the Q, have their device paired with the Q and then they can add songs, modify the playlist or even stop what you're playing and play what they want (this is where I see fights happening).
Seeing this is a bluetooth function, you shouldn't have issues with neighbors who happened to pair with your Q modifying your device. There could be a slight security issue though. In theory if someone pairs with your device and are good hackers they may be able to hack into your Q, since your Q is attached to your local network, then this person could possibly get to your local network. I'm hoping that Google has built some good firewalls between the bluetooth accessibility and the wireless networking.
Google Glass
It seems that Google is preselling prototypes of Google Glass to participants at Google I/O. Google Demo'd their new very cool glasses based device with a skydive stunt (Google Glass Skydive). The skydivers jumped out of a zeppelin that seems to be a constant on the San Francisco skyline. If you haven't seen the video yet, you can watch it above.
Other
Google is also pushing Google+, Google Drive (like Dropbox) and now Chrome for the iPad. I've been using Chrome on my mac for a few months now and I'm liking it. I never liked Safari on my mac and Firefox was very slow. What's cool about Chrome is that all my saved passwords, bookmarks, etc... are now available on ALL my devices. This is very similar to what's coming out in the next versions of Safari and iOS6. The concept of being able to start up where you left off without regard to device is coming to us quickly, in the next few years you'll be annoyed when you have to remember where you left off when you go from one device to another.
BlackBerry
Well how does BlackBerry compete with all of this? Well they don't, they announced a loss of 28 cents per share (well above even the worst estimate of 14 cents per share and making the average worst estimate of 3 cents per share seem paltry). RIM is in serious trouble, they aren't even in the same league of Apple and Google and with Windows 8 coming out soon, RIM seriously needs to consider who to sell their patents to and then shut the doors. RIM is doing it's best to be the next PalmOS. In premarket trading RIM is down 15% to $7.75, this is from a high of $17.57 in January this year and an all time high of $144 in June of 2008. I feel bad for the developers and people who work at RIM, but the leaders refused to open their eyes to the needs of a modern society, they never thought that desire to use an advanced platform would trump the need of 100% device security.
