Agreed. I don't know if it's just me, but Helvetica looks rather bad on Windows. I've found that Segoe UI almost always looks more pleasing, and yet Helvetica is omnipresent on the web (partially because of Twitter bootstrap).
I can't verify this, but unless you installed Helvetica manually, windows installations won't have it and will fall back to whatever is specified next in the family (usually Arial or the default Sans Serif).
