Capacitive screen is not better than resistive screen, they are just different, like orange and banana.
Shockproof phone would be a good idea, but it's a rarity in these times.
Processing power doesn't matter much when OS uses too much resources for 'nothing', during a stand-by.
Larger screen would be a liability for a mobile device, but alternatives - such as cinema-style projector - would be welcome for the rare times when large size of screen is preferred (such as, wanting to watch a movie with others on a camping trip - you just don't bring a laptop on a camping trip, it's too heavy, fragile and power-hungry).
Seriously? Any mobile computer is relevant in 2013, as long as you push it to its limits - most companies don't understand the meaning of attempting to reach for the moon, the sky, the stars beyond this galaxy. The possibilities are infinite... I wonder, will Fujitsu ever become a well-known telephone manufacturer? They mostly make Android phones, such as Raku-Raku. They are also presumed to produce the world's thinnest smart-phone, and show off waterproof models...
Best wishes.
