There are three things that could be game changers:
- 1.Cellphone as a computer, docked to a monitor and a keyboard/mouse.
- 2.Battery life of a week in a smartphone.
- 3.Super cheap. (Currently, symbian is the biggest OS worldwide, if you add symbian and S40 together, because it's cheap. See the real stats
The cellphone as a computer is something that might happen, and might benefit those smartphones that come with a full-blown OS (and here is an opportunity for ubuntu). The user would plug the device to a monitor and a keyboard and start working. We already have 1.5GHz processors, +1Gb RAM, and graphics chipsets that support OpenGL. We might see in the future clever ways to dock the smartphone into a monitor and keyboard (maybe wireless displays are in the future, but I doubt it because of bandwidth required). Maybe a dock that has the shape of laptop, only it provides the keyboard and display, but nothing else inside.
Android and iOS might be at a disadvantage for that, because those OS's weren't borne with desktop grade multitasking, file management, etc. (android has multitasking but only has windows in some samsung products), iOS wants you to forget that files even exist.
Smartphones already have: gps, bluetooth, wifi, 3g, accelerometers, compasses, gyroscopes, sd storage, hd displays, opengl, lots of RAM, more than 16gb storage, etc. What more could you add to them?? They are almost a PC, so why not use them as a PC that already has the capacity to fulfill most casual users needs.
On the cost issue, for WP8 or BB10 to take the market, they need to learn a lesson from cheap android phones and cheap S40 phones, that cover most of the needs of its users while remaining affordable, and even sometimes having more battery. If they don't come up with sub $100 devices (with subsidy), they are simply not going to penetrate latin america and india.
