Well, folks are beginning to be talking about this Edge effort in the past tense now .....
Half way there in time, only 1/4 of the way in dollars .... stick a fork in it, it's done.
================
What did the Edge campaign
really do?
Folks are now talking and thinking about CONVERGENCE as the core idea, same operating system same files on all devices and they are spinning it net-based a la Chrome and Drop Box and such for holding all your data.
They also note that Acer and HP and Dell have all uncorked 21" to 24" vertical display touch screen Android devices in the last month. Some are monitor-like, some get flat or get propped with a stand. All have a battery to keep content alive during transport. Such could be the "desktop" part of an Android convergence with your phone or tablet being your #2 device.
RockChip is selling large screen tablets in the orient using their custom cooked "windowing" multi-screening type Android system. They are being used as desktops by the oriental users, sometimes sent through a cable to the family TV. Rockchip's stuff allows up to 8 open windows and the resizing of the content seems to work pretty much 100%.
Google has done Chromecast now -- and that is still shaking up the television industry pretty good as it is a right scary to the Comcasts and Time Warners of the world. My phone company has suddenly dropped having to have a land line phone to get high speed internet for $29.99 .... Time Warner cut $10 off our monthly bill to keep us from jumping ship completely ..... because they KNOW we can do it now.
Chromecast as a device to enable convergence is already here, but there is no OS that drives towards that goal yet.
Google has been being asked when they are going to merge Chrome OS and Android as they have promised repeatedly that they are going to do "sometime".
Folks who watch Google internally note that internal email traffic about mouse/keyboard/touch with multiple users and multiple windows has increased of late.
Sometimes you sense a perfect storm event is coming .... ARM chipsets have the horsepower now to do a desktop. Chip supply is finally good enough to support all the phones, tablets, etc. etc. Demand for phones is tapering, tablets are still increasing but not at the terrible peakish rate it was going at. Microsoft is sidelined right now, Apple is quiet and Intel is still pushing vapor, mostly. The Linux kernel is completely intergrated with Android (and the Android pieces are joining into all the mainline distros as by and large they are quicker and less processor intensive).
ARM and Linaro have pushed all the final bits and pieces of 64 bits into the kernel and the driver libraries. They are refining things and fixing bugs as they crop up. (yep, the Samsung octa-core deal was both a bug and a needed refinement, both were done inside 6 months).
Linux and Android are practically speaking unified as even the finger control systems in Linux for tap & screen manipulation are the Android based systems now. Convergence is actually occurring naturally, with nobody at the wheel really directing it.
Convergence and Android -- Google, are you listening?
