I have always used tower computers. From my very first, which was a 40 MHz 386 I bought in April 1992. I put some files on floppy disks when we worked in groups in certain college classes (I don't think many students had laptops back then). I graduated in June 1997. (Funny story, when I first started using computers with Word Star 4.x back in 1988 at one of the various University of Cincinnati computer labs, we had to use a floppy to reboot some of the older PCs.)
My last job featured company laptops on carts with car batteries. They used very custom software to manage inventory at a warehouse. It was quite needless to bring your own laptop.
So I've never really been in a position to need a laptop. Not as a college student, and not in my working life. Now, I am working on an older Windows 7 computer. All I need is to surf the web, handle E-mail, sign up for electronic billing and keep track of my household expenses in my spreadsheet. I can do this with MS Excel 97 or Excel 2003. If my hardware dies, I can do all of these things under Linux, with "Crossover Office" that lets me run Office 97 and 2003 with no problem.
I still don't really need a laptop. And I can still get the "clicking" style keyboards, much more durable, I think, than the keyboard on a laptop computer. And my monitor is 10 years old, works perfectly, and is quite large and easy to view.
(I also like selecting my own parts -- Seasonic's absolutely fanless 460W PSU, Radeon 6770 video card, which is the second fastest card ever made that can function as a completely passive video card. I like the "look" of fins like a motorcycle the card has.)
