I use Everything search ALL THE TIME.
I have tried using several other similar tools and I hate them all with a passion!
Everything search is faster and seems to take very little resources to work.
Because I use it so much, I think it is only fair that we all pay *something* (something very small) to use Everything. And for goodness sakes don't make the mistake of charging too much.
I suggest "dirt cheap" - just like most iPhone apps - i.e about 1 or 2 dollars maximum.
In fact personally I would go further. I would actually make the older and/or slightly cut-down version of Everything completely free and only charge for the very latest version. On the down-side, if we are paying real money for the software then the developer(s) would need to keep developing the thing.

P.S. I also strongly suggest that the name if Everything is changed to something more searchable (e.g. "Everything Desktop" or "Everything Search"). I find it very hard to write or say sentences like "I think you guys should use Everything" or "I love Everything". Somehow the capital letter gets lost!
