For some, not all. I want my phone to be really pocketable. For me 3.5-3.7 is about right, 4.0 is about max. 4.3 is better for viewing sure, but it's just too big to be comfortable in my pocket or in my hand when used as a phone. It's only useful if I want to take it with me. Perfect phone form to me would be generally like the N900 with a slightly larger, about a 3.7-3.8 resistive screen, but overall a little thinner and lighter.
