OK, I'm wondering what manufacture's really mean when they say "multi-touch?"

The Dell S2340T page specifically mentions 10-point touch.

The ViewSonic TD2220 page doesn't specifically identify what they mean by multi-touch, but early reviewers call it a 2-point touch

The Acer T232HL/T272HL page doesn't specifically identify what they mean by multi-touch either.

The Microsoft Surface RT page identifies its multi-touch as being 5-point

Of course one would assume more is better, but what's your take on 10-/5-/2-point? Will it really matter much in Windows 8 for basic touch functionality?
