More than 20 startups and a few long-time telecom firms showed their latest wares to a group of about 350 press people last night at the Majestic Hotel in Barcelona. One of the more interesting items on display at the Showstoppers event was Novatel's HSPA/WiFi hotspot device, the MiFi 2352, which combines HSDPA/HSUPA with WiFi.
