PowerShell having standardized tab completion of flags/arguments is really nice, but it's worth noting that both bash and zsh support pluggable completion. It's one's choice of tools, and the lack of completion therein, that's the real sticking point. Home/end work on every machine I own, though I know that some machines (some Macs, specifically) have issues unless they're configured in the terminal emulator.

(I try to use PowerShell when on Windows. I genuinely like it--just kinda wish it was a little easier to write-on-the-fly, it's very verbose and typey and Tab is just far enough away to cause some wrist strain. ;) )
