Such limitations drive some users to upgrade to more mainstream editions of Windows 7, but many are discouraged by the additional expense -- and rightfully so. Among other benefits, netbooks are attractive because of their low price, and doling out $79.99 for an "anytime upgrade" to Windows 7 Home Premium is rough.
Starting April 4, participating retailers will offer upgrades from Starter to Home Premium for $49.99. Likewise, users of Home Premium can upgrade to Professional for $79.99. The promotion will last through July 3.
