Is 7" the new 10"?

7" devices are a rage.
After the success of the first 'wave' of 7" devices (1st Gen. Kindle Fire, Nexus 7), and the iPad Mini cannibalizing both iPad AND iPod sales for Apple, the 7" (to 8") tablet category seems to be taking over the tablet market.

After playing with 7" devices for a while (Both nexus and iPad mini), I can definitely understand why. The form factor is simply more successful than 10" tablets. Easy to hold with one hand (iPad Mini feels as light as a kindle), good enough to work with (Thumb type is possible) - Seems like this is the spot for tablets.

So, while 10" tablets are getting more and more laptop-like (Windows 8 convertibles, for example), 7" devices will get retina-quality screens, and probably become the new form factor size for tablets.

The untapped computing power

Now that cloud computing has taken over the web, it's time to think what would be the next step. Considering that the cloud providers are making money out of renting CPUs and storage. But there's already a lot of CPU power and storage connected to the web, and not being used most of the day.

This thought kind of takes me back to a '97 project called seti@home. That project used home PCs to parallel process radio signals from space. And though users didn't gain much from this project except for a thank you mail, times have changed since.

My wife, who has a day job, has a PC connected to the internet, operating all of the day. Imagine you can rent your computer for processing power or storage. Such network infrastructure already exists, and it would be pretty simple to install a client which receives jobs or lends storage for a cloud based network. As most search/ image processing/ big data analysis engines use map reduce and distributed storage nodes, such a network could provide a reliable, viable alternative to current cloud providers.

Been doing a lot of thinking about this lately. Who wants to join me and implement such a network?
