The Microsoft Courier is the most exciting, innovative product that has yet to be released. I'd begun to worry about whether or not it was vaporware. Thankfully, Engadget has just received word that the digital journal will be hitting stores in the second half of 2010.
Sources claim that the device is less than an inch thick and weighs a hair over a pound. When closed, it won't be much larger than a 5X7 photo. The Courier appears to use the Tegra 2 chip and runs the same OS as the Zune HD/Pink, which likely means Windows CE 6. You won't be seeing any of that under the Courier's gorgeous, notebook like interface.
As heard earlier, the Courier is said to have a webcam and handwriting recognition. Buying one will give you access to webspace where you can regularly upload your journal in a bloglike manner. There will also be a headphone jack, so this thing will be able to play music. Launch is set for Q3 or Q4. It can't come soon enough.
