Today I finally bought a kindle DX on ebay, after struggling so many days. Of course, I bought from the seller who asks for the cheapest price, but when I paid for it, I found I was charged 28 dallors for tax. I was quite surprised. I did read the discription carefully, which doesn’t mention the tax. I checked the location of the item, not in michigan. Why do I need to pay the tax? Finally, on the shipping and payment page, I found an anouncement about the “sale tax”, which says “Seller charges sales tax in multiple states”. Click on it, a table shows up and one can see people in michigan is charged 6% of the price for tax. I didn’t notice it, didn’t even have the idea to check it when I placed the order. My heart was broken! =_=! But the seller did ask for a cheap price. Even with the tax, I just paided 10 dollars more than the cheapest one available on ebay and 40 dollars cheaper than the Amazon official price (50 dollars cheaper if counted on the ebay bucks I earned). So this is still not a bad deal. But if I noticed that, I can save 10 more bucks. Take this lesson, my buddies.

It has worked very well for me till now, but it has not been updated since 2004 and recently I found some features that crimson editor does not have,such as code folding, really useful. So I want to switch to a powerful, up-to-date, extendable and cross-platform editor. Between vi and Emacs, I chose the later one. Emacs is not easy to learn, so I just want to learn some basic features firstly. 1. Switch between buffers, buffer and minibuffer, and modes. One does not need to change into a special mode to input the content in Emacs (This is one reason why I did not choose vi), but Emacs does have a minibuffer to take some complected commands from the user. And in Emacs one can have many buffers and each buffer has a mode (not the same "mode" in vi). So have to learn what they are and how to switch between them. 2. Basic editing, such as creat new, open, save, and close file, copy and paste, search and replace ... 3. F...
