Confirming preliminary reports, Apple has formally introduced Joint Venture, a special support program for small- to mid-sized businesses. The service requires buying a new Mac and paying at least $499 per year, but the latter covers up to four other "systems," which can include not just Macs but iPhones, iPods, iPads or even Cinema Displays. Up to 100 systems can be brought under Joint Venture if a business is willing to add the extra "uplift" fees to membership dues.
