1. The Apple iPad - My thoughts
2. Apple develops its first CPU: the Apple A4
- Snapdragon from Qualcomm latest: QSD8672 dual-core Cortex A8, up to 1.5GHz, integrated cellular and GPS, 45nm, full HD video, availablein 2H 2010, most common now is 1GHz, not full HD
3. IPS LCD - huh?
- Developed by Hitachi, Hitachi and LG make them now
- In-plane switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time. Its name comes from the main difference from TN panels, that the crystal molecules move parallel to the panel plane instead of perpendicular to it. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic wide viewing angles and good color reproduction.
- Initial iterations of IPS technology were plagued with slow response time and a low contrast ratio but later evolutions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market too.
- Also: blocking more transmission area, thus requiring a brighter backlight, which will consume more power, making this type of display less desirable for notebook computers.
- LG most advanced today: Enhanced IPS E-IPS 2009 Wider aperture for light transmission, enabling the use of lower-power, cheaper backlights. Improves diagonal viewing angle and further reduce response time to 5ms.
4. Anti-Apple cartoon: Probably not far from the truth
5. Despite lack of DX11 hardware, NVIDIA gains ground in GPU wars
7. Update: OnLive responds to our article in a blog post
- OnLive calls me a n00b
- Quote: "If you are more than 1000 miles from an OnLive data center, then the round trip communications delay (“ping” time) between your home and OnLive will be too long for fast-action video games "
