rjek: 'what would the advantage be over using one off-the-shelf'? A number of users (maybe a sufficient number to justify it commercially) might prefer to pay a premium to have a working system 'out-of-the-box', including accessory drivers and storage etc. The advantage for CTL - or any other supplier - would presumably be that there would be no hardware development costs/risks. Speaking personally, I would be willing to buy a beagleboard or similar device and load RO5 onto it once the Cortex-A8 port is sufficiently developed, if that is the only way to get an up-to-date system, but I would certainly consider paying a premium for the complete OS/hardward package from a reputable supplier.
AW: more speed would be nice, but a Cortex-A8 RO platform would be a) portable; b) under active development. That would tip the balance for me.
