Well this is silly isn't it??? Windows Phone 7 DOES have a built in scientific camera in landscape mode it auto switches from basic. That means you hold it horizontally in a vertical orientation facing yourself just in case you haven't figured that out either.
I seriously hope that there are better apps out there for Windows Phone 7 than what the author of this article has found. Half the apps listed here are pretty much the same thing, just for different languages.. like a translator for Japanese, oh and now one for Spanish, oh and here is another amazingly unique app that translates Chinese.. come on.. Most of the apps listed are hardly exclusively useful to students anyway.. Lots of people of all ages and walks of life need translators.. duhh..
