Look at the new iPad. Battery used to be like 25 watt hours and now it is ~43 in the new iPad. Battery still fits in the same space, just more condensed and packed in. Still gets the same battery life. Totally doable.
Honestly I would kind of like to keep the same design. Mainly because then I could put in my own SSD and have the hard drive in the optical bay.
Not just bigger battery in a new design, but also a more condensed battery.
And I definitely think apple will be the first to bring high resolution screens to laptops. Everybody else is too afraid to do that because no PC manufacturer wants to innovate or bring something new. Especially when it could potentially bring their prices up, and we all know that the low price is the only thing PCs have going for them. I think Apple will be the first to do it without making the price go up one penny.
Just out of curiosity, can you name some applications that take advantage of OpenCL and don't take advantage of CUDA? Because I can name a few that only take advantage of CUDA without even thinking, and the ones I am thinking of are very widely known and used. Can't say the same for OpenCL.
