Oh hey, that looks like a laptop. Technology we have had for more than a decade.
Don't get me wrong, I think the iPad is "nice" and I'd certainly have one for browsing in bed or while taking a dump but I won't pay $500+ AU for the privilege. Productivity, or doing anything useful is simply impossible with an iPad, either through incompatibility or limitations of the built in hardware.
Why craft products like this keyboard to give a false impression that you can actually do work "on" the iPad? You're simply better off with a cheap and chunky laptop with good specs or a MacBook Air for the prestige in addition to a competent smartphone.
At least then you're not trying to fool yourself and everybody else.
when people say you can't do work on the Ipad, it means THEY can't do work on the Ipad. For example, I run a website business in which i have 2 reps (including myself) supplied with ipads. From 1 single device, they go to my clients, take the photos of the product with the ipad, upload the photo and the info/data to the website, and it all auto-syncs to my Ever-note account hassle free. If i DIDN'T"T have Ipads, they would all be using stand alone cameras and have to upload all info ONCE they got home to THEIR computer which could be filled with spyware and viruses which would compromise the website log ins etc. the ipad works incredible for me and for many other people i deal with,talk with, and do business with. I love getting "all" my work done from 1 single device. Sorry it doesn't work for you.
To be fair, the ASUS transformer has sold pretty well I believe. it's about the same as this, although has a battery in the keyboard to give extra usage when it's connected.
Also, the netbook market is almost gone, so the cheap laptops are now around 14 inch screens. The 11inch laptop market and netbook market has decreased a lot since tablets came out. I don't know if this can fill that niche though because one of the best things about netbooks was the sub $400 (or even sub $300) price tag.
So why will this sell? because for many people the iPad is the coolest thing they own and it's part of their image, just like a designer purse. This is a cool accessory and it has an Apple logo on it. It'll sell, just watch.
