I smash this phone on the table and it's fine. Sony says they have competitions with people throwing it as far as they can and it still works fine, it doesn't even get scratched. Have fun with that. It can stay under water for 30 minutes at 1m depth, so it's not just splash proof, it's waterproof.

ARM Powered Windows 8 RT Samsung Ativ Tablet shown for the first time. It looks like it can work with a keyboard dock, my guess is the price is going to be $499/499€ without the keyboard, to be confirmed.
Qualcomm is doing huge work optimizing Linux and Windows on their S3 and S4 processors, trying to get as much performance out of the hardware as possible. Rob Chandhok is in charge of software at Qualcomm and in this video he talks about some of the software challenges that Qualcomm is working on to optimize software on their processors.
This demo of Windows 8 RT on Qualcomm S4 seems to be very smooth. There are a few bugs here or there, but overall, it looks quite smooth to me. I think Windows 8 on ARM is going to be more popular than Windows 8 on x86, yet I think that Android will remain far more popular than all forms of Windows.
