Although I know a lot of people older than 25 that have an iPhone the iPhone demographic probably does have younger and 'casual' members as Palm, like RIM, comes from a business/professional background.Despite what some people here seem to think... this is actually a very good move we should see a lot more new web driven applications in the near future, and maybe even some that are developed by Apple. All Palm needs is one or more killer applications others can use patents too you know and there you have it... a competitor to the iPhone (let the flaming begin).
Also, iPhone developers might want to expand and cash in that extra check. It might I haven't checked also be a little easier to write a WebOS app.
p.s. I am also wondering about the age of iPhone users, because that must be younger people I don't know a single person above 25 with an iPhone (all Palm users I know are a lot older and less willing to install dozens of useless applications).
