"3-surfing through screens is also possible on windows pressing ALT-TAB"
But can you configure it to change the screens immediately? I think it's much, much faster to switch to right screen, when you can see the actual screen when browsing with amiga-m than trying to figure out from small icons and text which is the right program to jump with alt-tab.
As said before, I love too the shift/alt/ctrl + arrow keys/del/backspace behaviour on Amiga. It's so quick to modify url in browser with shift-del for example... than paint wanted area with mouse or removing chars by pressing del long time etc. And getting wanted shell command from buffer... you don't have to browse all used commands with up arrow, you just can enter couple of first chars from wanted command and then press shift-up. This I'd really like to linux etc systems too!
Other thing is that different windows won't take too much space on screen. There isn't that much useless stuff on windows like on Windows

Like menus visible on every window and too much extra space here and there...
And datatypes are great IMHO. I don't know if there's yet similar system on other platforms, but it just great that you can add support for new formats for several programs by installing one datatype. Remember the PNG issue? With datatypes Windows's browsers would have worked with png years earlier

Amiga's browsers had support for it way before Windows

I also like that enter accepts the current input, not the whole window

Like in settings on Windows... enter means OK and closes the whole thing. I like Amiga's way when enter leads you to next option. It's logical from text editors for example.. you write line, press enter and you'll be on next line. It doesn't save all the changes and close the editor
And disk requesters and volume names on Amiga are just great. You can for example take CD out while reading it. Requester pops up and asks you insert that particular CD in drive, but you can insert some other CD, do the stuff with it, remove it and then insert the original CD on drive and original task continues. Try it with Windows for example and get in the blue screen h*ll
