I have a Surface and an iPad, so I completely understand what you mean about file management. But if you do find yourself in an iOS world - the killer app for file management on iOS is actually Dropbox. Organise your dropbox account on another computer -filing everything as it should be, then it will sync up to your iOS device, and you can access everything as required, including pdfs, images, word docs, etc. It's not perfect but it does work well. I also have another file management app which allows me to connect to my NAS via the iPad. This is also very useful. Of course, neither are necessary for the Surface, but I prefer a lot of the consumption features of the iPad. Web browsing on the iPad is superior because of screen quality and the browser being much more adept at gestures.
