Just starting??? iCloud is a really nice looking, tightly integrated setup. MS could do well to take some of those ideas and apply them to SkyDrive if they want it to be more than just their take on Dropbox.
I would love to have my SkyDrive show up in Office on my phone like it does for photos or as a shared folder on my laptop in Office. It blows having to nav to my SkyDrive on the phone and not being able to just directly save a new document. The web apps are nice and having the ability to open it in Office without having to download it, save it, then re-upload it is nice but it could be easier.
Being a student I worry about flash drive failure, hard drive crashes, or any other slew of random computer excuses people give for not having their homework so I do everything on SkyDrive.
As for Bing maps, I've never had a problem with it but I've also never been a fan of navigation. I look at a map with a route from one place to the other and follow the line making turns where the written directions tell me to. I don't like being told where to go because I never remember landmarks that way. Actually, the Bing nav is perfect for someone like me.
It searches great too. I want to find Dion's Pizza? I hit the magnifying glass, type it in, hit search, swipe once to the left. Boom, nearest Dion's Pizza. Click the name and I can call it, get directions to it, or go to the website. Easy peasy. When you call it it even holds the name in the call log so you can go back to it or save it to your contact list without having to type in the name or anything.
It is a little pickier than I like about punctuation and stuff though. Dions will turn up 0 results while Dion's will turn up all 10 of them around here.
