>I actually do not like Finder and prefer Windows Explorer. I always find myself forgetting that I can't create folder's in the save dialog.
Many programs have a new folder button in the save dialog box on OSX.
Unfortunately the save dialog box lacks any context menu functionality, there are a few parts of OSX where context menus are missing, which is an annoyance.
Another thing is how finder will cut short long file names if it lacks the room to display them, in small icons, list or column view. Explorer will not. This is extremely annoying if you have a folder full of long file names of documents or media files.
On windows though I find I start missing expose, I don't think expose is a perfect solution, it takes too long to recognise the window just from a thumbnail of it. But in some situations it's easier than dealing with a cluttered task bar. So I'll find myself looking for an expose function forgetting to keep track of the task bar in windows.
