Robert,

I must say I like the responsiveness of Philips (through you) *a lot*  
on this list. This is exactly what many of us embedded consultants 
really need. Philips has been very low on my "design in" list before. 
Mostly because of the low interest for us who design solutions for 
others but never buy a lot of components ourselves.But I think this is 
about to change.  I hope Philips will be as good as Microchip and others 
on samples and app. notes in he future. You are definitely on the way...

Keep up the good work!!!
