Special Interest Pavilions have long featured both up-and-coming companies,

attendees with particular interests can experience first-hand the very
latest Macintosh technology for specific market segments in a cohesive
setting.

event on the East Coast. The special interest pavilions are a focal point
at the Expo for Macworld attendees seeking out technologies and solutions
in a specific market segment,” said Neil Ticktin, CEO of Xplain
Corporation. “With a mission focused on serving the specific communities,
these pavilions have vendors of all types and sizes showcasing the best the
Mac has to offer.”

The pavilions contain a number of new companies that have never exhibited
before at any Macworld event. Across the board, the majority of exhibitors
in the pavilions are announcing and showing new products on the first day
of the show. Attendees can stop by for more information.
