If you're after interactive use, then by all means define and use your own aliases (or functions) as you see fit. It'd be a pretty crappy idea to not do that. Custom aliases in scripts you share with others are not a good idea, of course, but that's firmly in the scripting aspect you note, not the interactive shell use. That being said, even with commands being long, tab completion does an absolutely amazing job of shortening what you type. Also it's usually just the first command of a pipeline that doesn't have an alias because after that you tend to use the same few cmdlets over and over again (%, ?, select, ft, ...), which do have short aliases.
