they kill the notion of "general purpose computer" for the masses and each computing "device" sold to the public is a locked down single purpose appliance
Have you entirely missed the iPhone and the iPad? I think the thing the techie crowd is struggling with is the iPhone and iPad represent a paradigm shift, where you do replace "general purpose computer", but instead of with a single purpose device it is a device that becomes whatever you need. When I need a compass my iPhone becomes one, same with music player, e-mail client, calendar, web browser, internet radio player, map, RSS reader, coupon barcodes, ticket receipt, credit card scanner, calculator, I could go on forever. Instead of general purpose it is becoming task specific - and I for one welcome this. I look forward to the day when I can unlock my front door, start my car, read my sales report, than start a phone call all from one device.
That's stupid because the iPhone does not differ substantially from other smartphones.
iPhone hardware does not differ substantially from other phones, but the user interface is way different than anything out there - and Jobs wants to keep it that way and keep it consistent. Sure it isn't as different now with Android and WebOS, but when the iPhone came out there was nothing with near as slick and usable system.
