I got wap, I use it for Pill reports every now and then (not having a computer). Yeah, you could say its a waste of time, but hey, its the first generation of mobile internet blah (isnt it?), and it provides a glimpse into the future, and, answers that question that we have with every techological breakthough (such as the phone, TV, the computer): Will we use it, and will we need it? And yes, once its not at the pong videogame-of-mobile internet stage, it will become something of great use in the future. Thats my uneducated perspective anyway.
As for 3G, from reports I heard, isnt that a bit of a dud? I heard that while its got great bandwidth, the network cant really handle all the traffic it would generate if it caught on. - Disclaimer: I'm not in the industry and dont really know what I'm on about, this is just an uninformed opinon. : )
