3090 in terms of feature set is quite dated and limited in current market. It will eventually phase out as PMW3310DH replaces 3090 in the high end LED segment. To many benefits to ignore.
At least the 3090 can now get a SROM that is focused on array performance rather than CPI.
Not sure why this matters if newer DSP can effectively calculate accurate CPI. If you're suggesting a lower cost/lower DPI 3090, I can't see it working out with current pricing structure. They'll probably end up offering a public version of Logitech's AM010 if anything were to happen.
Is an internal oscillator better than an external? I would think that an external crystal oscillator would be best.
Honestly depends on quality of unit.Edited by Skylit - 11/21/13 at 10:22pm
