Well, I only have the RT, which is 99% of the time adequate for my needs. That said, I would like to have the following which, I think, would make it a perfect machine for me:
A very capable and robust Mail client - could be Outlook, but not necessarily so. It should, however, be integrated with a/ the Calendar app. In this connection, I have been looking at TouchMail and that looks very interesting too - though I am not sure if it is integrated with a Calendar!
VLC - I believe a VLC app for RT is on the cards.
Another browser - while IE is quite good on the RT, another browser (particularly on the Modern UI side of things) would good to have - if not, on the desktop would be OK too.
Edit:
Ideally, I would also like some of the apps that businesses release - like those by airline companies, banks etc. - to be designed for the RT. But I am not sure if that is covered by your post. If yes, then for sure I want a Barclays banking app. I would also like a few apps for a couple of hotel chains and airlines that I use often when traveling.
