I've said it many times. I'd love to be able to charge my phone from my tablet, because, let's face it, your phone is way more important than a tablet, plus your slate has an enormous battery compared to said phone. Well, Sony's finally gone and done it. You'll be able to charge your shiny new Xperia Z from your svelte Xperia Tablet Z. Awesome.
Of course, you'll need a double-ended microUSB cable to do it, but this is pure genius. Your tablet has a much, much bigger battery than your phone, so why not allow you to use it as a massive battery pack if you want? I mean, if your tablet runs dry that's OK, but if you're stuck in the middle of nowhere with a dead phone, that's just not cool.
So thank you, Sony. By waterproofing your gadgets, and now letting you transfer battery charge from tablets to phones, you're showing that you're finally thinking outside the box. More of this kind of thing and you might even win me over. [Xperia blog via Ubergizmo]
