Another edition of potpourri where I surface some of the more interesting HF/usability links that have crossed my path.

• The blog Touch Usability finds a great video of Bill Buxton discussing Designing for Ubiquitous Computing
• Smashing Magazine illustrates a simple and effective UX tool (the rainbow spreadsheet) to visualize user behavior during testing
• The Atlantic Magazine wonders how kids will be messed up by using touch screens so early!  Experts weigh in…
• Usability guru Jakob Nielsen does not like how web searching is done today.  How would he change it?
• Finally, knobfeel, an audio equipment review site that focuses on the feel of the knobs on the equipment…that is all.
