Motorola CEO’s debuted Linux-based “Rokr” and “Razr2” models at a Manhattan event with new top execs last week. Finally, Moto, after four years of hiding Linux mobiles in Asia and South America, brings the Penguin to your pocket in the US.

The metal-finished Razr2, 2mm thinner than the record-breaking original Razr, runs 420MB of memory with its 500MHz CPU, a large 2″ external screen, plus a 2MP cam, says PC Mag. ‘Crystal Talk’ was said to boost call clarity and automatic text-to-speech readout with Linux models, as per the UK’s Mobile Today.

The MotoRokr Z6 is an MP3 player when closed and a phone when slid open, per Linux Devices. If Yanks take a shine to the no-keyboard iPhone form factor, Moto has an already-shipping keyless Linux phone ready to bring over from the Chinese market.

When combined with Palm’s dance towards Linux, it’s time to ask; Are you ready for a penguin in your pocket? Join the discussion.
