BARCELONA, MOBILE WORLD CONGRESS 2012 –When Asus first announced the PadFone at Computex 2011, they did so with a level of gleefully cheesy showmanship that set Apple fans sarcastically hailing chairman Jonney Shih as South Korea’s next Steve Jobs. To many Apple fans, the PadFone — a laptop with a tablet inside with a phone inside the tablet — represented the worst of the rest of the industry’s “kitchen sink” approach to beating Cupertino. If we can’t build a phone to beat the iPhone, a tablet to beat the iPad, or an ultraportable to beat the MacBook Air, why not beat one device to beat all three at the same time?

But it’s wrong to dismiss the PadFone just because of cheesy showmanship, or because it’s not likely to topple Apple’s three pillars in one go. We had a hands-on with one, and it’s far from a cheesy device. In fact, it’s actually a little marvel.

BARCELONA, MOBILE WORLD CONGRESS 2012 — On the surface of things, Asus’s Eee Pad Transformer Prime is just a wonderfully swell idea. Why have both an ultrabook and tablet when you can have one that is both? What if you could take your iPad, snap it onto a keyboard + trackpad, and have a MacBook Air?

It’s a nice dream, and, in actuality, the Transformer Prime is a beautiful piece of hardware. But the challenges aren’t hardware: they lie in software. And in software, neither Android nor iOS is yet up to the challenge of driving both a mobile and laptop OS. But after Windows 8 sets the bar higher, they both could be.

BARCELONA, MOBILE WORLD CONGRESS 2012 — Fujitsu’s made the first Android phone that I, as an iPhone lover, found myself drooling over… which makes it a doubly good thing that the phone in question is waterproof. And not just waterproof! As thin and light and as perfect in the hand as a dream.

The only problems? Because of Fujitsu’s bizarre way of selling their devices, this phone, which has been on sale in Japan for months, doesn’t even have a set name. And forget about getting one Stateside. How does a company make a phone this beautiful and then have no idea how to market it?

BARCELONA, MOBILE WORLD CONGRESS 2012 — Samsung is serious about its Galaxy Note hardware, and has had a rare fit of intense product focus. The Notes are being pushed as artists’ devices. This much is obvious from the artists painting people’s portraits in the Samsung booth, and the caricatures covering every surface like a kids pre-school scrawlings plastered on a proud parent’s fridge door. But Samsung has also got some great developers on board.

BARCELONA, MOBILE WORLD CONGRESS 2012 — Scalado, most recently seen removing people from photos like a cold-war-era dictatorship, today showed me some of its other fancy photo-processing apps. Scattered across Android, Windows Phone and Symbian, but mostly Android, there is an embarrassment of cleverness in fast photo processing.
