I'm certainly keeping an eye on other handheld platforms, but it comes down to two things :- does the platform have native code USB host support, and is it popular enough that more than a handful of people are going to be interested in buying it ?
If not, then I'm probably better off spending time improving ArgyllCMS instead.
(But then I'm not convinced that more than one platform is needed - Android is cheap and widely available - if you want to measure color on the go, you can solve your problem right now, with no further work on anyone's part.)
