The only thing that the new T-Mobile Sidekick (Danger Hiptop) is missing that would be nice is bluetooth, although with USB, IR, and most promisingly, an “Accessory Port”, hopefully a bluetooth add-on will be coming soon. Hmm… with USB available, it may be not too hard to write drivers for a USB ethernet adapter. That a simple nat or proxy, plus a crossover cable might give you a simple bootstrap for ad-hoc internet access when your laptop is wi-fi-less. Just thinking out loud… (time to d/l the latest version of J2ME)

I’ve already raved about the form-factor and the pricing, but one more thing that really separates the Danger (and hopefully all next-generation devices) is the ability to do true multitasking. Stewart Alsop writes in Fortune that he believes that the Danger’s business model is risky (their taking a percentage off data access only), but I have a feeling that might pay off – bigtime. Once people discover how useful (and addicting) live internet access (specifically IM, but also finding directions and getting movie schedules, etc) are, it’ll be a paradigm shift like the cell-phone or even widespread net access itself: we’ll never imagine how we lived without it. Think about what that shift was like.
