As someone who does a lot of 3D modeling, and who has done professional graphics and game development, I am worried because affordable, powerful systems may become out of the reach of the average person. Cellphone and tablet chips, generally have 1/10 of the processing power than can be found on a desktop computer. You may be able to draw a few lines and rotate a few objects on tablet, but in 3D CAD can be quite demanding. Machines have parts. Circuit boards have traces. Processors have a piece of silicon with lots of little blobs of stuff on it. All of these add up to a difficult problem for even tablets. HD video editing can be demanding.
Beyond the hardware, so little is expected from even tablet software. Is it really a miracle if we can cut and paste? Could you run an entire business on your tablet, a tablet that could have 300 times the processing power than a desktop of the 1990's business system? The problem here is we expect too little. As an example, PhotoShop Touch cannot even edit a 24 mega pixel image from a $500 Nikon D3200 entry-level DLSR camera, but PhotoShop, PaintShopPro or the Gimp could do that an a netbook.
Cellphones and Tablets, Android and iOS are application-centric, not document centric. When we work, we often need to exchange information between programs, and that is not easy to to on iOS. In Android, every program has it's own weird file chooser. We don't have proper shared font folders for these, in fact they tried to get rid of the parent/child folder/file metaphor, which is fine of you never plan to organize anything using a computer.
So many cell/tablet centric computers a married to the cloud so tightly, that you cannot work if your connection is slow, goes down, or something bad happens. The sobering part is: a war or natural disaster could mitigate any productivity of cloud users by offering a single point of failure. Please don't put all of your eggs in one or someone's basket.
What we needed was one OS that worked on "devices" and computers, the difference being than one CAN work autonomously, and they other is a new metaphor for a old idea, the dumb terminal. Microsoft screwed up Windows 8, twice. They should have never made XP into Vista, and now it's too big, let that be your coffin nail. Windows 8, was not about doing the work that was needed to be done, it was about using the code you had. Apple's has tried integration, but remember, Apple likes application centricity. Gnome tried so hard, but we want a 2 pane file manager. We want to use this stuff for desktop applications. Mint chipping undermining Ubuntu Linux throne, suggests that we still want a command bar. We still want multiple window. Where would you have been in your life, if you never compared anything to anything else?
Are we becoming a world of chattering people who can't do anything creatively with one of the greatest machines ever made?
[Lately, I've been having problems even finding laptops with dedicated GPUs. The Intel Integrated GPUs do not seem to have a full OpenGL implementation, and the going gets slow when you need just as much CPU as GPU.]
