yes sony needs to free the capabilities of its reader other wise they are going to loose this battle too despite being early adapter of this technology as they did with sony ericsson and p800. they are reactive and not proactive. they are providing features only when others are providing it. if they can provide following features they can be winner-
1. any programme like calibre on reader itself so i dont have to depend on computer.
2. wi-fi and 3g without any restriction.
3. good pdf support with suitable size of screen.
4. no geographical restrictions.
sony can not become number1 just by talking they need to provide breakthrough features as iphone did and now almost all phones are just following it.
