Re: (sic)

"We're convinced Windows 7 HAS an exciting and powerful offering for our business customers, but we want to hear from you," (don't see a problem. They're not selling just software, but a lfe-changing experience)

"We're convinced Windows 7 IS an exciting and powerful offering TO our business customers, but we want to hear from you," (and anyway, Windows is not an offering, it costs money)

"We're convinced Windows 7 WILL HAVE an exciting and powerful offering for our business customers, but we want to hear from you," (makes the last bit confusing and well, it's just.....yuck.)

IM(ES)HO, I would've bunged in a 'that' after 'convinced'. Also, I might have used a full stop instead of a comma (also in the preceeding paragraph). Call me old-fashioned.

Loving Windows 7, though!
