Wi-Fi gadgets turn on heat
Perhaps it was wishful thinking, but a couple of years ago you would have thought that by now you would be able to sit at any city cafe, park bench, airport bar or a cafe hotspot across the country and hop on the Internet via a free Wi-Fi connection. The painful truth is that such ubiquitous Wi-Fi is still years away. But several companies are betting enough people have wireless routers at home or use public hotspots to support a handheld Wi-Fi device that doesn't double as a cell phone. The Sony Mylo COM-2, the Nokia N810 Internet Tablet and the Zipit Wireless Messenger 2 all let you save on cellular data service fees while leaving your laptop computer in its case. And each is directed at a different segment of the market.
