Why pay $30 per month? Starbucks isn't the only place with WiFi. Many communities around the world are now offering free wifi. And in your office you should have or may soon have wifi for free. You might occasionally have to pay at an airport or hotel, but that isn't $30 per month. And the Palm Tungsten C is anything but bulky. Also, the Palm website has them for $399.
Not that I'm trying to sell Palm on you. I'm just trying to correct some misconceptions.
