There's nothing wrong with a general pocket computer without telephony. I'm just wondering why no one else is making them after four years of Nokia doing so.

If a product's going to be successful, it has to either break into an existing market or find a new market. How can maemo 5 devices do either of those things if they stay pretty much the same as maemo 4 devices? What will change that will suddenly get people interested in the device?

The iPod Touch is cited on here as an example of a successful pocket computer, but most people don't buy it as a computer, they buy it as a media player. If you look at the customer comments for the iPod Touch on Amazon, most of them discuss media playback as the main feature. They might mention the other stuff too, but it's clearly not the driving force for their purchase.

This is a typical review for the iPod Touch on Amazon:

"As an iPod music player the iPod Touch is fantastic. As a photo browser it's great. As a video player it is, screen size limitation aside, incredible. And as a game platform it is super fun! Throw in PDA capabilities and WiFi connectivity and you've got a major winner."

...does that sound anything like a typical maemo user?
