Iphone, uidesign and PKM hybrid Discussion

Question: Recently, I have read articles and TV Related to the iphone. I really have an impulse to buy an iphone. A great ingredient lies in its attractive "interface" and touch operations. It seems that a good software is very important to use the UI to lure users and users into a "beautiful" experience.

A few days ago, I collected an article about the iphone, which focuses on the UI design and other related content. Remember that this article also contains a link to the iphone short film. I saw CCTV's "World Weekly" last night and remembered the "cool" UI and operations of its advertisements to improve the software design.
 
Of course, the previous method was to search for "Web page history" or use Google. It was very difficult to find the original article. Therefore, I developed the "dot matrix Personal Knowledge Base Management System". I only input the iphone, and I can quickly find related articles. This is a good feeling.

I have been promoting PKM recently, hoping that more people will experience this feeling. There has been a conflict between free and paid services. Maybe one day we will choose free, at least not in the near future, because the cost of RD is still relatively high.
PKM registration is not much, so it may turn to development KM (for enterprise ).
