Starbucks and T-Mobile seem to be pushing entertainment offerings (The press release doesn't seem to be posted yet but should turn up here eventually.): For the month of October, hot spot users in Starbucks can watch streaming video of classic blues performers and listen to some blues music.
These kinds of entertainment offerings may draw a different crowd to the hot spots, in addition to the business users. T-Mobile has also sponsored some live streams of concerts, encouraging folks to watch at a Starbucks hot spot.
