Eh, I kinda agree with him. I hate it when my phone is a computer too.
I do appreciate that Apple has spent some time making things snappy. I understand this isn't always the case (iOS 4 on iPhone 3G for example).
It sounds like he's complaining about being told that he has to update this, scan that, defrag something, and turn on his firewall for crissakes. My netbook is far more interested in telling me that whatever programs I run at boot have a new version out than just opening whatever program I need to use badly enough to have turned the thing on.
And that's the deal here - firing up a desktop operating system in the first place requires a certain amount of work and carries with it a certain cost that makes using a desktop operating system for short periods inefficient.
If you want to, for example, check the weather, for many, it's going to take five minutes of computer stuff to support a minute of the actual task.
Now, someone is going to come in and tell me that Ubintows 7X Meerkat boots faster than an iPad on a triskadecacore i8 with SSD, but I say that's not everyone's experience.
Further, the iPad doesn't expose the finer points of computer configuration, use, and management. The Slashdot crowd has a lot of people whose work exists in that stuff. I'm one, and time with an iPad or CR-48 makes me feel like I can't get work done, but that's often because my work is "computery." For people whose work is word processing, it doesn't matter so much.
So, Slashdot, if your work is working on the tool, it's easy to see a tool that doesn't need your kind of work as a tool that prevents you from doing work.
