世界首部膝上型電腦 重十公斤
筆記型電腦講究的就是輕薄好攜帶，但世界第一部所謂的「膝上型」電腦重達二十四磅，十點八公斤。要是腿不夠粗壯，千萬別放在腿上使用。
這部電腦是英國人歐斯朋在一九八一年推出的，電腦就叫歐斯朋一號。
當時最先進的「小巧」型電腦，有兩個五點二五吋軟碟插槽，隨機存取記憶體六十四K，唯獨記憶體四K。歐斯朋一號還有一個五吋的黑白螢幕和可拆式的鍵盤。
由於是先進產品，比桌上型電腦小巧多了，所以當時一部就要價一千七百九十五英鎊，大約折合八萬台幣。
推出以後，銷路還不錯，第二年的銷售量是十二萬五千部。不過，接下來就被幾個美國大廠牌打敗了。

Released in 1981 by the Osborne Computer Corporation, the Osborne 1 is considered to be the first true portable computer - it closes-up for protection, and has a carrying handle. It even has an optional battery pack, so it doesn't have to plugged into the 110VAC outlet for power.
While quite revolutionary, the Osborne does have its limitations. For example, the screen is only 5" (diagonal) in size, and can't display more than 52 characters per line of text. To compensate, you can actually scroll the screen display back and forth with the cursor keys to show lines of text up to 128 characters wide. 
The Osborne was designed with transportation in mind - it had to be rugged and able to survive being moved about. That's one reason that the screen is so small - a larger and heavier screen would be more susceptable to damage.
The two pockets beneath the floppy drives work great for floppy disk storage, although the Osborne modem also fits perfectly in the the left pocket and plugs into the front-mounted "modem" port.
Designed as a true portable computer system - it can be considered airline carry-on luggage, and it will fit under the passenger seat of any commercial airliner. 
While the Osborne was a good deal at $1795, it also came bundled with about $1500 of free software:
- CP/M System
- CP/M Utility
- SuperCalc spreadsheet application
- WordStar word processing application with MailMerge
- Microsoft MBASIC programming language
- Digital Research CBASIC programming language
The Osborne was a huge overnight success, with sales reaching 10,000 units a month.
In September 1981, Osborne Computer Company had its first US$1 million sales month.
這玩意也叫做「Laptop」或是「Notebook」？
我看根本就是All in One的桌上型電腦！頂多是附上一個大箱子，可以「手提」，應該稱為「手提電腦」才對！
