What you mean is, People that are doing serious creative work don't like be handicapped with an under-powered device with slow access and small display. I'd hate having to work with handcuffs on too, especially when I up against a deadline. Mobile devices will most likely continue to be a "companion" to desktops for "serious work". Not a replacement. Find me a developer of content who would give up their mult-display,quad core, 64bit machine for an iPhone/iPad/Android to write apps, webpages or presentations, and I'll concede.
