ASUS PadFone review
It's been a long ride for the PadFone. ASUS' last smartphone was the Android 2.1-powered A10 from two years ago, then five months later the company ended its smartphone partnership with Garmin (though they're still friends). The next thing we knew, the outfit was openly considering Windows Phone, but obviously nothing came to fruition despite its E600 engineering units floating about in the wild. Meanwhile, a bunch of Android Eee Pads started entering the market to get a slice of that hot tablet pie. Eventually, the PadFone shocked the industry at last year's Computex (remember our brilliant mockup based on the teaser pics?), but ASUS went on to miss its Christmas launch target, allowing it extra time to rejig the phone's software and design. Then CES and MWC went by, with the latter hosting the official launch event to unveil the PadFone's final design and availability date. This time, the new April target was missed by only three weeks, and shortly afterwards we got hold of our retail unit from Taiwan, which is still the only place where you can get hold of the product. But enough with the story. What we want to know is whether ASUS' courageous and unique project has all the right ingredients to squeeze itself into a market now dominated by the likes of Apple, Samsung and HTC. Most importantly, will the company set a new trend with this two- or three-in-one form factor -- in the same way it did with netbooks -- thus taking the Android ecosystem to the next level?

ARM unveils Cortex-A7 processor, 'big.LITTLE' computing
Fancy a glimpse of the future? That little psychedelic beauty on the right is ARM's brand new Cortex-A7 processor. Its spec sheet might not seem so colorful at first glance, because it doesn't really do things any faster than existing high-end smartphone processors. However, this UK-based chip designer isn't known for bumping its gums, so it pays to look a little deeper. For a start, the Cortex-A7 is built using a 28nm process that makes it five times smaller and more efficient than the current-gen Cortex-A8. It's also cheap enough to power sub-$100 handsets, so we could be pulling GSII-like tricks on budget phones within a couple of years. Is that it? Nope, there's more: perhaps the most important feature of the A7 is that it can be combined with much higher-power cores like the Cortex-A15 side-by-side on the same chip. This allows a super-phone or tablet to switch between two totally different processing units depending on how much power is needed at the time. ARM calls this "Big.LITTLE" computing," and a similar concept is already in use on NVIDIA's Tegra 3 (aka Kal-El) SoC, which we'll see imminently in the next Asus Transformer. However, the Tegra 3 uses five identical Cortex-A9 cores, whereas a device that mix-and-matches the A15 and A7 could potentially deliver higher highs and lower lows, giving you speed when you need it and amazing battery life when you don't. How cute is that? Full PR after the break.
Daily Mac App: gfxCardStatus
Some newer MacBook Pros have been packing dual graphics cards for a while now, with the ability to dynamically switch between them -- integrated for battery life and discrete for performance. It's often tricky to know which card is currently in use as the switch between the two is seamless. That's where gfxCardStatus comes to the rescue. Sitting up in your menu bar, gfxCardStatus shows you at a glance which card is currently active, but more than that, it actually allows you to manually switch between the GPUs. A drop down menu provides you with three options: Integrated Only; Discrete Only; and Dynamic Switching, which is the system default that lets OS X decide which graphics card is required. If you want to save as much battery power as possible, leaving it on integrated only will ensure that the power hungry discrete GPU doesn't fire up. On the other hand if you want maximum performance all the time, then discrete only will make sure the most powerful GPU is fired up. For most situations OS X does a decent job of managing power considerations, but if you want a little more control, gfxCardStatus will let you set up GPU power schemes to define which chip is used depending on power source. gfxCardStatus is one of those little apps that's both useful and doesn't get in your way. You won't need it a lot, but if you're on battery power and you want to keep working for as long as possible, the little menu bar app can be a life saver. It's freely available (donations accepted) to download from the developer's site and is Lion-ready.
