Well the Android core devs were ex BeOS engineers, as were the iPod touch engineers (which later became the iPhone), so I’d assume the engineers knew what they were doing. Sadly, the DotCom crash in 1999 removed funding from BeInc, we could have had these devices a decade earlier.
At one point there were half a dozen ex-Be Inc engineers working on Android... Dianne Hackbourne and Ficus Kirkpatrick come to mind, but there were more.
