More powerful? Yeah, sure. But honestly, many companies have made more powerful versions of Excel over the years and most of them have gone to the wall.

If you think of power in a different way, that of empowering users who typically have little or no technology experience, things get a bit more interesting.

Google Docs and Zoho are still viable products despite from a CS perspective being significantly less powerful.
