You guys sound like you've been asleep for the past decade.
MS developed MSBasic for the Amiga and did not buy it... even when it was on sale!
Like all new hardware their PDAs and Phones need content to sell them. MS seriously need AA and AA get a good distribution deal quicker than anyone thought.
Even though MS have the Xbox they still sell dev systems to companies that support rival consoles.
As the retail outlets increase it will look more attractive to other developers. It may also help AI get old Commodore/Amiga back catalogue onto PDA/Smartphone.
With the government watching them MS cannot force the same agreements onto other companies like they used to.
Wake up!!
