This may be significant
Skype on Linux. Two very distruptive technologies coming together on (what one would hope will also be) low cost deveices.
You have to admire the Skype guys - putting together a fantastic marketing machine and tons of partners. And all using ye olde Windows PC as a Trojian Horse to get customers used to it.
Linux of course has to benefit enormously also and with these portable devices you might say that the next target is Symbian- or at least Windows Mobile
I wonder if these will be a s cheap or maybe even cheaper than the eeePC.
Using these low end devices as an entry point for linux into the mass market does sound very much like Komatsu's "Surround Caterpillar" strategy that worked so well in that past
