I hate touchpads. They're more difficult to use than trackballs and mice. And they're put at the wrong place, making typing difficult. (My thumbs easily and accidentally touch that pad while I'm typing. To avoid that means using an unnatural posture that would make me tired faster.) Too bad that it's hard to find notebooks without a touchpad nowadays.

Digitizers on the onther hand are great at stan> this- which is why any serious CAD/CAM is driven by them. I can't agree more. Graphics designers who need to use drawing programs a lot would also throw the mouse away for digitizers. It's simply "impossible" to draw anything properly with a mouse. -- Lee Sau Dan §õ¦u´° ~{@nJX6X~} E-mail: danlee(a)informatik.uni-freiburg.de Home page: http://www.informatik.uni-freiburg.de/~danlee

Of course, together with my passive knowledge of written French. German has many French loans (though not as many as naturalized English words that has a French origin). Also, the knowledge of some Japanese (a verb-final language) helped a little bit: relative clauses in German are verb-final. blmblm> That could be.

I don't believe in this. I think it's doable, if you would dig into phonetics or a person with good phonetics knowledge could help you get rid of the accent. The major factor, I believe, is the amount of time you can devote to learning a language. Before puberty, you don't need to earn for a living. You don't have too much homework at school. You simply have so much time. Further, you're driven by the motivation of communicating with your playmates, watching TV, etc. There is a strong motivation and lots of time to devote to. blmblm> You are probably right that individual effort varies, and blmblm> that being in an environment where you *have* to use the blmblm> new language makes a huge difference. The amount of time you can spend on learning it is also an important factor. (Not having the pressure to make a living for yourself and your family also makes learning more enjoyable.) -- Lee Sau Dan §õ¦u´° ~{@nJX6X~} E-mail: danlee(a)informatik.uni-freiburg.de Home page: http://www.informatik.uni-freiburg.de/~danlee
