Pictured: 18 Form Factors of Windows Mobile

All this talk of the iPhone 3G reminds me how Windows Mobile is the most robust platforms in terms of form factor choice. But how many form factors are there? I set out to find the answer.

If we just focus on keyboard type, there are a total of 16 form factors to Windows Mobile. That’s a huge amount of choices. But of course, having 16 form factors doesn’t detract from the substantial list of problems we have with WinMo in its current iteration, but it is indeed an important consideration when choosing a smartphone platform.

Click the below chart for a high-res image.

Looking beyond iPhone, which of course only has one form factor, BlackBerry has two currently with two on the way (candybar QWERTY, candybar SureType, flip SureType, and no keyboard), Palm has two (candybar QWERTY and no keyboard), and Symbian does a bit better with a handful (candybar T9, flip T9, clamshell QWERTY, no keyboard, Down-Sliding T9, etc).

That said, what’s your favorite keyboard form factor?

Update: Added number 17 (thanks Steve) and number 18 (thanks srigopal). Any others?
