Everything about that blog is wrong
Much as I love the idea of smartphones and hate myself for thinking the iPhone looks sleek, I would never, EVER buy one. Why? There's too much crap on them.
I want my phone to send and receive SMS and MMS messages and make and receive phone calls. Beyond that I really couldn't care less what it does. Hell it can even lose the clock, I have a watch. Not because I'm a technophobe - because I'm not - but because I'd prefer a simple and reliable device that has decent battery life rather than some unholy hunk that has to constantly deal with GPS, WiFi, motion sensor technology, touchscreen (which is THE most pointless innovation EVER) cutting its battery time in half. (I currrently have a Samsung U800 which is very nice, gets me a low contract and does the shit I want from a phone).
If I want to work, write and do internet stuff I'd use a computer. My laptop is very nice, but far too big and heavy to use on the move, so I have an Asus EEE that I got as a bargain (new for half the retail price - yes, from a legitimate store!). £150 and I can browse the internet, yes. But I can also take photos off my D50 on the move - directly useful to my job - for moving to a memory stick or e-mailing.
But to say they are solely web-based is just... wrong. My EEE has, yes, e-mail, Firefox and Google Docs. However, it also has the full Open Office suite and GIMP image editor.
Short of connecting to the company network, it has more functionality, both online and off, (and seemingly more RAM!) than my office computer.
I'm definitely picking up an anti-netbook vibe here but for the life of me I can't understand your reasoning.
