Gartner ReportThe 770 has it in spades, especially when it comes to usability ...Business WeekThe ThinkPad 770 and the Tecra 750 are both very impressive machines, but the IBM wins my vote for a huge display and excellent ergonomics. The ThinkPad 600 features what may be the best keyboard I have ever seen in a laptop.PC ComputingYou've come to expect these kinds of top-drawer technologies in a ThinkPad, but usability is where this machine truly shines. Feather weight and First Rate usability. If you've got a say in the matter, get the IBM ThinkPad 600. ...the ThinkPad's [600] usability suffers no peer.
ThinkPadComputer Shopper "offers the best
humanengineering we've seen in a home PC." "... All the Aptiva models offer the striking look, above average performance, and user-friendliness ... Additionally, the Aptiva Access program lumps many system settings often found in disparate locations into one simple to use application ... The EZ buttons on the Aptiva are similar in concept to the Compaq Presario, however, the Aptiva features are more extensive ... IBM's ScrollPoint mouse closes the door on the scroll bar ... "
Wall Street Journal "... .. looks better and creates a better workspace
arrangement than any other PC I've seen ... The IBM Aptiva offers the best setup ..."

Was ist User-Centered Design?
Vredenburg, Isensee, and Righi (1999),Making Products Easy: A Practical Guide to User-Centered
Design Techniques and Technologies.
"An approach to designing ease of use into the total user experience with products and systems. It involves two fundamental elements - multidisciplinary teamwork and a set of specialized methods of acquiring user input and converting it into design."
