Ah! I love Asus, This is a company that think outside the box. I would be worried the phone get all scratched out by putting in and out the pad slot.
Not really. "think outside the box" is creativeness, but it lacks true innovation. For the true definition of innovation, you can search on internet (not wikipedia). Simply, innovation is bringing ideas to the reality with a big effect to the company's performance or the society.
Why did I say that? Asus has tried to show many many positive advantages of its products to people. They are true advantages, I agree, but just on the surface.
There first quad-core device (TF201) sounded great. First quadcore, IPS+ super bright display, gorgeous aluminum body with keyboard and quickest ICS update. But the quad-core had IO issue, performance was sooo laggy, bad build quality (cracking even aluminum), loosen screen and light bleeding, no GPS and weak wifi (metal body and very bad cheap wifi radio from Azura), mono sound and super buggy update. Oh one of the biggest Flop.
The first Padfone: it's brilliant idea becoming true after more than a year and many people were bored. When the device came out, it's so heavy and buggy (resolution conflict between phone and tablet pad). Expensive price.
The first Full-HD Android Tablet: long delayed device also. Like TF201, it was PR as a powerful device with a simirlar story: Full HD screen IPS+ super bright display, 1.6Ghz quad-core, changing in design with better GPS and wifi, quickest update. But performance wasstill bad (garbage Tegra 3 IO issue), updates were still buggy, screen was still loosen or light bleed, wifi chipset was still Azura's. Oh luckily this time it's still much better than tf201.
Padfone 2: good device but too expensive. Keyboard dock was no longer available on Padfone series. This phone was "died" after announcing few months because of Padfone Infinity
Padfone Infinity: I had some Asus devices and I don't wanna try anymore, but this one seems to be good. Unfortunately, it's only available in some areas with small number. Price is sooo expensive. I think people will continue considering it is as something inside the art museum, not for use.
Overall, Asus always has great ideas, but it lacks of making comprehensive devices, good marketing with reasonable price, making the "creative ideas" cannot become "innovations"
