This one part has never seemed quite right moving from PC to Mac for me... I'm most used to Windows Explorer - the old XP style, working in a single window. I find that with Finder, to copy/paste or move files, I can't always just select files and paste/copy them to the new location... and some things seem to require having multiple Finder windows open and a drag/drop. Maybe I'm missing something in the process/workflow and its possible to solely work easily in a single Finder window? It doesn't seem to always allow you to do a copy or cut when you right click on a selection of files in Finder.
