nokia's Ovi takes on Apple's MobileMe with the new file sharing services as well as PIM functionality (calendar and contacts syncing) for Nokia's phones. Whilst this space is a huge market considering that each mobile phone provider has an exclusive and proprietary solution, I'd prefer to have a solution that works on all fronts - meaning, on Linux, Mac and Windows as well as on the iPhone, Windows Mobile and Symbian (and soon, Android).

I just wish that there is a native app that will allow users to manage their files, rather than using a browser on your phone. That way, you can keep a list of your files locally, without needing to go online and then going online when you already know which files you really need. Saves you time and money, right?
