No, that is not the issue.

The issue is how big the app is in whatever mode MOST USERS are/will be using it in.

I, for one, rarely used full screen mode (and what Peter says makes _some_ sense to me). Lots of posters in this thread sound like they often used full screen mode. Peter is implying that marketing assumes infrequent use of full screen mode. But, NONE of those is an actual indication of what most users are/were ACTUALLY doing (nor what new users are likely to do). The first two are anecdotal (ie: worthless in determining an actual generalized truth). The third is speculative.

We wont know which assumption is correct without a rigorous and well designed usability study. We don't know if the marketing team actually did one of those or not (I hope they did, but Peter hasn't revealed that to us).

What we do know: unless there is also going to be a tablet sized product line, our usage patterns of the devices will change. We don't know yet if that's good or bad. We just know it's going to happen, either because existing apps will be smaller, or we'll be moving to new apps that better fit the screen, or because we'll be changing how we do or don't invoke full screen mode, or .... etc.

(I'm sort of hoping that the RX-71 is a tablet ... but I'm also sort of hoping that the RX-71 is a netbook, or netbook sized tablet, to fit with that set of rumors)
