The Browser Breakdown
The growth of the mobile web and touch screens has created more browser diversity than ever before. I think it’s useful to categorize browsers into four major categories, along the axes of screen size and input type.

Probably the most growth is going to come in the large-screen touch category (mainly because it’s starting from the lowest place overall). If anything, I would expect the small-screen mouse input category (i.e. Blackberries) to decrease — but not to disappear entirely, because businessmen sure do love their physical keyboards.
Making web apps that work with minimal adaptation across all four quadrants is the challenge. (And you thought dealing with different screen resolutions was hard?)

If you’re interested, I have some stats on iPhone and mobile growth vs. “normal” computer growth that I got at AEA from LukeW. Remind me at work and I’ll pass them on to you
The right column is one of the reasons why I’m being such a thorn in the side about users with no mouse.
