I tried to update my iPhone 3GS with iOS 5.0.1 which was released on Thursday to fix a critical security hole and promise better battery life for iPhone 4S users. It seems Apple may have not sufficiently tested it before release. Not only my update failed, but also my iPhone firmware could not be restored at the first try. I tried reset via tap both home button and power off button and a different cable, and finally got the restored firmware.
Updated: strangely enough, after I restored the firmware, my iOS is 5.0.1.

Transformer Prime vs. iPad 2 vs. Kindle Fire vs. Nook Tablet
There is more than enough room for tablet players. Current estimates suggest tablet sales will increase on average 83% a year to 185 million units in 2014; RBC estimates Apple will sell 50 million iPads in fiscal 2012 (up 54% yearly) and 65 million in 2013.
Asus' newly announced Eee Pad Transformer Prime, the first tablet to feature Nvidia's new Tegra 3 quad-core processor. The Prime will get an upgrade to Ice Cream Sandwich. The Prime joins Amazon's Kindle Fire and Barnes & Noble's Nook Tablet as the latest set of tablet devices hitting store shelves before the end of the year. Ian Paul, PCWorld, gave comparisons between four tablets:

Intel and MIPS Bets on Android 4.0 Ice Cream Sandwich with 2012 Release
Android 4.0 Ice Cream Sandwich includes many improvements including a new interface and system bar that makes accessing and navigating through applications easier. Other features include an improved keyboard, integration of multiple email accounts, improved security, core application improvements, and near-field communications (NFC) abilities for mobile payments. It also provides impressive media processing features, such as face unlock, camera functions for quicker photo, live effect, enhanced Talk-to-Text, and photo editor.
It has already been shown to work on a smartphone with an ARM processor. HTC confirmed that the HTC Sensation, HTC Sensation XL, HTC Sensation XE, HTC Rezound, HTC EVO 3D, HTC EVO Design 4G, and HTC Amaze 4G would all be seeing the update to Android 4.0.
The new OS includes OS optimization for x86, so Intel architecture-based devices, can support it, according to Suzy Greenberg, an Intel spokeswoman. HP new tablet Slate 2 includes faster hardware including Intel's Atom Z670 processor, which runs at a clock speed of 1.5GHz and has accelerators to decode 1080p video.
MIPS is the third processor architecture challenging ARM in the tablet and smartphone space. Tablets with MIPS processors already support Android 3.0, which is code-named Honeycomb, and the company is porting Android 4.0 for tablets.

Xilinx ISE 13.3, Artix-7 and Virtex-7 XT
This release is another try to support Artix-7 and Virtex-7 XT. According to the company press release, a full custom precision floating-point support, including new bit and cycle accurate, single, double and full custom precision floating-point in system generator for DSP, is provided to extend productivity for DSP designers.
Artix™-7 FPGAs deliver the lowest power and lowest cost to address high-volume markets. This family is one of three product families built on a common 28nm architecture designed for maximum power efficiency and offers over two times the capacity, 30% higher performance, 50% lower power consumption -- and logic up to 350K logic cell density at lower price points than Spartan®-6 FPGAs.
the latest Virtex-7, 2000T FPGA, integrates 2 million logic cells, 6.8 billion transistors and 12.5Gb/s serial transceivers on a single device making it the world’s highest capacity FPGA. This is equivalent to 20 million ASIC gates.Virtex-7 XT provides larger block RAM (85.0Mb) than other Virtex-7 devices.
