If you have been wanting to do your work using Microsoft Office but not wanting to boot up your computer, maybe Microsoft Office for iPad can help. There was no mention of when it will be available but it seems that Microsoft is going to submit to iTunes App Store.
If the app is presumably approved by Apple, it will bring Word, Excel and PowerPoint to iPad (at a price of course). According to source, The Daily had a chance to try it. That means it is not just a pretty UI shown above.
