This is very interesting because P1 and Green Packet is working on a WiMAX netbook that should be available within next 1-2months.
I did not investigate on this further but I am making a wild guess that it might be the Acer Aspire One WiMAX Netbook or one of the Asus netbook.
Personally I am waiting for a WiMAX mobile device(as small as a mobile phone) to replace my secondary mobile phone, but then the current P1’s WiMAX coverage can’t offer me mobility, for now.
P.s: Check out the Green Packet website, they are hiding something.
