There were a couple of interesting things in the latest edition.

One of our divisions works on a display technology call Mirasol. As we all know, battery life is one of the most important issues with mobile phones, and the display usually eats a lot of that. Just like on your laptop, if you dim you screen, your batt life goes up. In talking about display technology, there was this interesting bit of info:

Screen Sizes and Battery Life
Handset Display Standby (hr) Talk (mins)
iPhone 3G 480×320 at 162 ppi 300 300
iPhone 3GS** 480×320 at 162 ppi 300 300
T-Mobile G1 480×320 (HVGA) 402 350
Palm Pre** 480×320 300 300
BB Storm 480×360 360 330
Samsung Omnia 400×240 450 390
HTC Touch HD 800×480 (WVGA) 680 420
** Not in original QMag article

Interesting that the HTC has the best resolution (by far) and also the best battery life.

And then there is a small blurb about some researchers at Washington University that came up with USB ultrasound probes that work with WinMo. So apparently in developing countries, doctors could use mobile phone technology to take an ultrasound. Pretty cool.
