A Swype-like keyboard (I actually use Google Keyboard's Swype mode, even though I own Swype) is a "must have" on my phone and has been for over three and a half years (since Swype beta was available on the original Galaxy Note).
While there are definitely thumb typists who can type quite fast, for me personally Swyping is significantly faster than tapping. I refuse to go back to that, it is bad enough things like passwords require tapping (although thanks to LastPass working with Chrome on Android, that too might be a thing of the past).
Now all we need is Microsoft to get with the program. Windows 8/8.1 still lacks a Swype-like keyboard and third party keyboards don't really exist. Kind of sucks on the Surface (you don't ALWAYS have the keyboard cover on).
