Most people do not see Android, Apple and Nokia devices as being any different. They all have big screens, cameras, web, email, etc... They don't understand specs, so they judge on what they know. They do know apps, so this is one way in which they will judge the use of a phone.
Now, nobody will use 300,000 apps, but everyone knows 300,000 is better than 100,000, or 2,000.
I completely disagree. Once a platform hits a critical mass of app support (well below 300k, still well below 100k and even below 2k though that's in the right neighborhood), bigger numbers are a net negative, IMO. A hundred thousand more apps is just a ton more garbage you have to wade through to find the very few good ones.
