That is the best idea! The Diamond does comes with Office like you said... That includes Word, Excel, and Powerpoint. If there was a small keyboard like the one you mentioned, this would be like a very nice "Limited to" internet/mobile/word-processing/instant-messaging/Calling/Gaming laptop. And when you think about it, it really isn't that "limited" after all!
I did like 20 Powerpoint presentations in my last class (end of class, 30min exercises - Powerpoint as a means to present Architecture ideas instantly). I wouldn't have to leave class to use the computer anymore. haha

Is this what you are talking about?

SCORE: This Keyboard works with the first HTC Touch. It supports Win 6.0. This means it will also support 6.1 because the Touch can be upgraded to 6.1 right? (Speculation - Pricey as well: $139.99)http://www.mobiletechreview.com/ubbthreads/showflat.php?Board=news&Number=29931AND:http://www.mobiletechreview.com/tips/keyboards.htmThe Winner???http://www.freedominput.com/site/index.php?option=com_content&task=view&id=116&Itemid=112Here is an awesome link that takes you through the Windows Mobile experience in a fun way... including Office:
