Fitbit Charge HR review

Since my Fitbit Force was recalled earlier this year, I’d been pining for a simple motivational aid.  Microsoft’s Band looks awesome, but it’s sold out as soon as they get another batch of units.  The Garmin VivoSmart had some interesting features, but lacks stair climbs (important to me because I do so much of that in a […]

Late last fall, when I was first contemplating replacements for my four year-old Dell Inspiron laptop, Netbooks piqued my interest.  I gave them serious consideration as a replacement machine, but there were three major problems: 1.

Mechanics

I have to agree with Elizabeth that the whole taking a phone call in the middle of a meeting is off-putting.  Some of my coworkers are notorious about this, often jumping to address a quadrant 4 domestic issue.  I do try to ignore any calls until after the meeting’s over.  One exception is if my spouse’s
