One Advantage of Ubuntu over Windows: File Naming

A quick observation here.  One thing I have noticed between Ubuntu and Windows is that when naming files, I haven't (in Ubuntu) run into any problems with file length.  I think the Ubuntu file name system even takes some symbols like the colon (:).  Also, another small but helpful and cool thing (to me at least) is that when renaming a file, I can leave the PDF open in Foxit and rename it without any issues unlike in Windows with Adobe (it may be just an Adobe thing, I haven't checked).  However, if you are sharing files with a Windows user, the Windows system can't/won't copy the files.
