FUD Zilla had a chat with Bill Henry, General Manager of NVIDIA's Mobile Internet Devices Division, and heard notebooks can't get any smaller than they are today. Not because it's technically impossible to create smaller notebooks, but because ultra tiny notebooks just aren't that convenient to do some serious work on.
Henry explained that for most serious individuals 10" or 12" is the smallest comforable size, but he also notes there's definitely a customer base for 7", 8.9" and 10" netbooks.
For most serious individuals 10 or 12 inches is the smallest comfortable size, but the 7, 8.9 and 10-inch netbook market has proven to have its customer base who want small and low-priced notebooks.
MID’s are something else and it looks like we all need something a bit bigger than an iPhone and smaller than 7-inch Eee PC. This might be a perfect device that would fit in your pocket, and at the same time, could do some serious computing and probably play HD movies via an HDMI cable. This is what Nvidia wants to achieve with Tegra platform and we hope to get some nice mobile designs with it.
