Apple, Bring Back the Butterfly Keyboard for Netbooks

There goes Apple, trash-talking netbooks again. Tim Cook, the company’s chief operating officer, had harsh words yesterday for the current crop of inexpensive mini-notebooks, calling them “junky” with cramped keyboards and bad software. “It’s a stretch to call them a personal computer,”IBM Laptop Battery, he said.


While I wouldn’t call all netbooks junk, Cook’s criticisms are valid. My biggest gripe with every mini-note I’ve tried is the tiny keyboard. It’s an ergonomic disaster. My hands aren’t huge, but I can’t type on these things for longer than an hour. So if Apple does enter the netbook category — and I believe it will, sooner rather than later — it should address the keyboard issue first.


Here’s my suggestion: Apple should bring back the “butterfly keyboard” — or a variation of it — used by IBM for a brief period back in the 1990s. For those of you too young to remember, 02K7054, ThinkPad A20, ThinkPad A20M, ThinkPad A21M,
ThinkPad R60, or those who were distracted by watching their stock portfolios rise and fall back then, the butterfly device was a fold-out keyboard featured on the IBM ThinkPad 701 series. It consisted of two halves; when opened it extended over the sides of the laptop,02K7054, thereby creating a more spacious keyboard than those found in competing notebooks at the time.


Called TrackWrite, the clever design generated a lot of media buzz when it first appeared in 1995. The fold-out keyboard didn’t last long, however, in part because the move toward larger displays made it irrelevant. (The ThinkPad 701 had a 10.4-inch display, similar to today’s netbooks.) I always liked the concept, though, and had hoped that IBM or another vendor would bring it back someday.


Now the time has come. The emergence of the netbook has brought back many of the ergonomic woes of early portables, including cramped keyboards and small screens. Would Apple ever license TrackWrite from IBM? I doubt it. The company’s pride and not-invented-here attitude would never let that happen. But you never know.


Some users may see the touch screen as a better alternative to a fold-out keyboard. I don’t think so. ThinkPad A20,A touch screen is nice for some things, and it’s a good fit with handheld gadgets like the iPhone. But for touch typists who write long documents for extended periods of time, a touch screen could never replace the keyboard. It’s too slow and clunky.


Voice input? Sure, someday. But not yet. For now, we’re stuck with the keyboard. So why not a fold-out keyboard for netbooks?

In relation to mobile phones, laptops and other portable devices on the application, the application of laptop battery power will be much more stringent requirements. Liu Minghui told reporters that Li-ion batteries Inspiron 9200 battery , Latitude D820 battery ,02K7054, ThinkPad A20, ThinkPad A20M, ThinkPad A21M,
ThinkPad R60, XPS M140 battery in automotive applications is different from other applications,ThinkPad A20M, the complexity of the car battery applications put forward higher requirements, such as in high temperature, humidity, vibration environment. In the application of electric bicycle on the requirements of energy while not as good as cars, but the requirement to adapt to the environment are not the lowest.


Jiangsu New Electric Vehicle Co., Ltd. Japan Center for electrical engineering research and development, Minister Wang believes that in terms of electric bicycles, and its poor protection, the dell battery , although in the plastic or metal casing inside the assembly, but only electric bicycle parked in the general car-room , to withstand the wind and the sun and rain, and are subject to seasonal changes in temperature. At the same time, as the bike, the road traffic is not necessarily a good road surface, so the requirements of lithium-ion battery waterproof and resistant to high and low temperature performance, anti-vibration performance, and safety performance should be higher than the car. Judging from the current situation,ThinkPad A21M,
lithium-ion batteries Inspiron 5000 , Inspiron 5150 in automotive applications has not entered the stage of actual business. Liu Minghui said that the majority of enterprises in hybrid and electric vehicles are still in the demonstration phase of product and not really in volume production. In contrast, lithium-ion batteries for electric bikes in the development of faster, have a certain amount of products on the market.


Industry believes that the long term, prices are not constrained the development of lithium-ion battery power problems, the current lithium-ion toshiba battery power constraints the main factor is the safety of people and products of their level of maturity concerns. Liu Minghui said that the safety of the battery need to go through rigorous testing, after tested in the factory through the practical application of the user to observe,02K7054, ThinkPad A20, ThinkPad A20M, ThinkPad A21M,
ThinkPad R60, if the test of time over a period of what the problem is not to say that it is a sign of maturity.


In the electric bicycle is also encountered similar problems, Zhang Yong told reporters that as a result of lithium-ion Compaq battery and control system itself imperfect quality, ThinkPad R60, many manufacturers in the early promotion of the product as a result of the use of mileage and time commitments did not meet targets, in the consumer who had a negative impact on the eyes.


Electric Bicycle with Li-ion Acer battery industry and the importance of more research and development investment, the product will gradually mature in the lithium-ion battery market faster development cycle. The lithium-ion Fujitsu laptop battery in the car market really need more time to start.
