I’m a pretty big fan of OneNote, and although I have debated switching to EverNote I always come back to it. I’ve been using it on the iPhone with some success and now Microsoft has released Lync shortly after porting OneNote over to the iPad and add SkyDrive functionality (limited) to the iPhone. IMHO, this opens the floodgates on what a business can do with iPhones and iPads as laptop replacements. I’m currently working on getting an iPad to use in this format so hopefully I can have plenty of test cases to write about. Maybe they will port Management Studio over so that we can use it as well. That’s going on the wish list.
I’m still waiting to get an iDevice on the domain to test with, but if you happen to try Lync on an apple device let me know how it is working out for you as I will hopefully be doing the same thing pretty soon.
