Yes now it is, it was like magic on the original iPhone.

there's a big issue with patents. they should protect how you get to a result and not the result itself.
if someone invents for instance multi touch he should patent how he got there. the process. how he got it to work. not the fact that it works.
others will need to develop multi touch if they want to use it but they will need to do some research for it and if they use the process that you patented then yes, protect it.
now it's like saying... hey, i've created the color red. red is unavailable from now on... even if you discover a new mix of pigments for it.
