The future is in ecosystem. Tech companies want all of your peas in one pod - their pod. I fully expect a Kindle Phone within the next 3 years.
I also expect Google to further distinguish their Nexus line of phones, tablet, and media streaming and tighten their ecosystem. Google Plus might not be "Facebook", but that is no longer the point. It's about having people in the Google ecosystem - Android, gmail, Google TV, Google Fiber, and so forth. Google is trying to take on the tech world and take over the world - once they figure out how to get money into their "Play Store" they will be set. Amazon doesn't help their cause, and Apple is still king.
Apple needs a social network and they need to be HANDS OFF aside from marketing it...even then, Apple doesn't get social. Ping was an absolute joke. They still struggle to explain iCloud to the layman, and they never really got MobileMe over with the public. iWorks will never beat Microsoft Office, but again, the tech world is in an ecosystem race and Apple just needs a killer social product that will really kill the competition.
I'm not a huge fan of Windows, but I feel like they are the dark horse that might surprise everyone. I have no stake in the console wars, but I see the success of the 360. The failure of the Zune led to the emergence of the Zune Marketplace, and the Zune itself lives on in Windows Phone 7 (and soon 8). Outlook.com MIGHT actually be successful in moving people away from gmail because it looks good and the domain is far more professional than Hotmail or even Live - I can put this on a business card. Metro is intriguing and their Surface tablet hinges on the price. The HP Touchpad should serve as a lesson to everyone (and Amazon and Google clearly learned) - you CAN NOT beat the iPad by matching the price. Even a spec'd out $300 tablet won't move units, but $199 and under is a sweet spot that all tablet makers should be striving for, along with a simple and sleek UI experience. Win8 has the UI, but I'm concerned about that price tag, but the ball is now in their court and I believe it's dropping in October.
Finally, I agree with Liquid regarding digital downloads, and I'll take it a step further and say that the Cloud is the future as well. The biggest hurdle to both of these are the residential and mobile broadband providers. Data caps kill any progress these services might provide, and the average residential upload and download speed in America is still embarrassing, though steadily improving. I am confident that Streaming/Cloud/Digital will take off like a rocket once a 20 megabit download AND upload speed is more common place and affordable to American consumers with no data caps on usage. That will finally allow people to stream anywhere and everywhere, and might convince those that hold out to finally cut the cable cord once they see that they have quick access to their favorite shows and movies online.
