1. at first is here any person, who changed long time used Scissor switches, to topre? and how happy you are about this? and I mean not typewriters, but peoples who also actively use shortcuts and text navigation.
I'm not sure whether you are referring to the usability of the HHKB layout, or the feel of the Topres vs the Scissor Switch. I can tell you that the Topre will beat any scissor (and even some mechanical) keyboards for quality of feel. The HHKB layout is great, I have no issues with it with anything, either Windows or Linux.
2. I'am programmer, and mostly windows user + vmware user with different linux distros, so I'am pretty often use page up down insert/delete and arrow keys - I liked idea when I can use it from the home row, and tried to convert my current keyboard to this mode, but my pinky very soon became very tired. is here anyone person who actively use photoshop, eclipse or visual studio and happy while using it with their HHKB? I'll try to notice again, I'am not type writer, I'am programmer who use fancy IDEs with lot of shortcuts, so while writing texts I'am also using shortcuts actively with FN+ buttons, will this layout work for me or very soon I got problems with my wrist?
It's hard to say. The HHKB layout is really optimized for the likes of Emacs/Vim. If you make extensive use of F-keys and PgUp/PgDn, you be better off with the slightly bigger Realforce 87U with dedicated keys.
3. and the last question, what is related in some way to first one, as alternative to HHKB I'am looking now into Apple Aluminium Keyboard Show Image
(http://www.zcover.com/IMAGES/Keyboard/Apple/AppleKeyboard_Wireless.jpg)
it's very compact, use Scissor switches and looks almost like HHKB. maybe anyone HHKB user tried it?
Tried one, has nothing on the HHKB. Apparently the chiclet keys have given many a person sore wrists.
