Just got a card in the mail from T-Mobile. Since I’m a customer I can get unlimited T-Mobile Hotspot access at all hotspots (most Starbucks, Borders, etc.) for $20/month on a month-to-month basis. That’s about 50% off their normal rate. See http://www.t-mobile.com/getmorehotspot.
McDonald’s is supposed to be launching their “get an hour for a meal” WiFi access here in San Jose soon. Mercury News said they’d be announcing something next week. See “McDonald’s serves wireless“.
