Martin Hajek — a designer who specializes these days in mocking up rumored Apple products with a greater or lesser degree of accuracy — has turned his talents to a new arena: mocking up how the newly announced Samsung Galaxy S4 measures up, size-wize, to the iPhone 5.

Its plastic chassis may feel cheaper than the iPhone 5’s glass-and-aluminum materials, but Samsung’s new Galaxy S4 smartphone actually costs significantly more to make. In fact, almost 20% more.

At one point during Samsung’s tacky Galaxy SIV launch event at the Radio City Music Hall in New York, the emcee — upon asking what the point of a screen that could react to gestures in mid-air without actually touching it, and being treated to a Greek chorus of answers from a constabulary of shrill, histrionic shrews — said of Samsungs new Air Gestures: “Okay, I see how that might be useful.”

Those words really sum up everything Samsung put up on stage tonight. I see how that might be useful.

The Galaxy SIV is a phone largely unchanged from the SIII. It’s a little thinner, a little lighter, a little more powerful. It has a bunch of new features. And all of them require a small one-act play on one of the most important stages in Manhattan to explain why, in a certain circumstance, they might be useful.

The Galaxy SIV is official, and it is a beautiful powerhouse of a phone with features unseen in any other device, but how does Samsung’s latest flagship phone stack up against the competition, spec-by-spec? Check out the chart below to find out.

Cheaper Android tablets are stealing the iPad’s market share.

There’s good news and bad news for both iOS and Android fans in the latest report from research firm IDC.

The good news (for Android) is that by the end of this year, Android will account for most of the tablets in the world, with a 48.8% marketshare to Apple’s 46 percent.
