There's an interesting article on guardian.co.uk about a study that suggests that Android adopters will struggle to maintain margins in the future, drawing parallels with the 'Wintel' PC market.

Although there are flaws in the study -

• more OS' about in the smartphone market than the Desktop PC (at the time)
• the concept of mobile carriers
• more cpu mfrs in the smartphone game

it still makes a good read. Oh and there's a couple of decent comments.

Maybe Nokia do know what they are doing in trying to retain their own identity.
