Cobblers... they're toys/gimmicks that sad gits buy just to be trendy, how do you do D.T.P. on an I phone ? where to you plug in the printer ?, where's the video output to connect up to a monitor ? etc.. etc..
As I say nothing but toys/gimmicks that mugs buy just to try and look cool, sad really... 
There are smart phones with video output (composite or HDMI depending on the phone) & USB On The Go (which allows USB printers to be plugged in ). Eventually they will be cheap enough to be standard on all phones, but at the moment people don't want to pay money for something they will never use.
Most phones come with either bluetooth or wifi, which can be used for printing.
The software isn't necessarily there, that would be where you could make a difference. However you'd be better off hacking Android around.
DTP? really? when was the last time anyone actually did DTP?
And after people realised Netbooks were just a fad and you can't do any real work on them so are not actual replacements for a 12" laptop the sales naturally will tail off.
Go into any shop today and see if you can find a new laptop for sale that can run the 2002 game Battlefield 1942....didn't think so
All you get today are Facebook/youtube capable dual core multi gigabyte bollox really, and this sours it for people who believe laptops are ONLY capable of this level of performance.
The Asus 1016P is a good netbook for homework/web/social etc. It's not for gamers, but you shouldn't expect it for the price. There is an nvidia ion based version that is more expensive and will do better for games, but if you're in the minority of people that play PC games then yes don't buy a netbook.
However, you need to visit different shops. There are very capable systems out there, you'll pay more than that the price of a desktop (like you always did) and you won't get as good a performance as a desktop (like you always did) but you should at least be able to get a reasonable experience with games from 2008.
My laptop is nearly three years old and it can run crysis & I'm looking to upgrade because it's slow compared to what is available now.
