bit late to the prom (and in pink) is Sony Ericsson's newly announced PC300 Mobile Broadband PC Card. Yeah, as in PCMCIA, not ExpressCard. Their new radio-slab brings HSDPA, UMTS, EDGE and GPRS data at speeds up to 3.6Mbps. It will automatic handoff between HSDPA/UMTS/EDGE supporting tri-band 850, 1900, 2100MHz HSDPA/UMTS and quad-band 850, 900, 1800, 1900MHz EDGE/GPRS. And yeah, it's PC and Mac compatible... although you can't buy a new MacBook (and a growing list of others vendor models) with a PC Card slot anymore. Fortunately, the antenna is integrated -- a nice touch if you've ever snapped one off while puttering about staring at your laptop's screen. Expect the PC300 to hit in Q3 globally -- about the time we hope we'll need cards supporting 7.2Mbps. Hey, a boy can dream.
