Sorry Felix, a 4×5" sensor would deliver at 5 µm pixelpitch: 20320 × 25400 = 516.128 MP, so something between 1.5 and 2 GB data - per picture. Looks like eceryday purpose, doesn't it?

 

I was not talking about everyday purpose and large format cameras are not for everyday purposes anyway. 1.5-2GB of data could be handled easily in a few years and large format film (at least the color stuff) is disappearing slowly. It's a small market, but it's there to be taken.

 

Innovation is not "more", "higher", "bigger" - that's evolution. Innovation is doing things totally different.

 
Hm that's actually not true. Innovation doesn't have to be radical and it's definitely not the opposite of evolution. Relatively small improvements like "more", "higher", "bigger" or "more efficient" can also be innovative, they are just not of the radical "creative destruction" type. 
 
Maybe that is also part of the "Apple problem". They are constantly improving their MacBooks & iDevices and some of these improvements, e.g. in mainboard and battery layout, have been quite innovative. They just seem unable to create products that are radically new and make a big splash like the iPod or the original iPhone. And that might actually be something that positively correlates with their growth. Bigger firms are often less successful at such things..
