Yes you missed it.

Im sorry to say but in your dreams there might be so, its clear
that you dont have had the experience you get from beeing involved
in millions of units purcasing.There is a big difference between
vendor and manufacturer you can only get indepth info from the
manufacturer "if" they are willing to give you the info, and that
is certanily not the case always.Anything thats baad for sales, 
they wont even give you a hint.This is nothing new it has been
there all the time and will continue to be there. This is not
a particular named manufacturer issue, not even a engineering
issue,its a money issue.

I think its the opposite. And Atmel offers more I/O.

Offcourse they are but they are faster in IO as some users say!
Peculiar isnt it!

That has nothing to do with the LPC2106 GPIO issue discussed earlier.
I get the impression that you sound like more of a philips sales 
men not an engineer!

What as advertising to do with the discussion about GPIO?
Absolutely nothing!Please stay to the issue bob you get
confused otherwhise!;-)

You see,different things concerns different people if you have 
noticed, some concerns SPI other about the CAN others and i about
GPIO, some about software etc, etc.

You are talking about sales techniques im and others are talking
about engineering issues, who cares if the Dodge Hemi draws a
litre or a million litre a european mile! Whats the point contra
LPC2106????

Now Bob, im getting realy tierd ,what you  are saying is a platitude!
You could had swap what you previously said for:

"My boeing 747 is so powerful, it draws 10000 litre per second and
"we marketing it as super powerful and 350 people can fly with it.

There is simply no point,you are comparing apple and grapes
using sales terms!

> Please continue to provide challenging feedback for Philips

Bob, i dont buy your tesings,only this single one because of 
your complainits about wining wich in turn is not very constructive
either.

If you don't understand the content of folks mailings regarding
problematic issues, ask for futher explenation. If other peoples
style of writing dont fit you or it triggers your wine nerve
simply ignore mail in question. If it do conserns you, focus
on mail contents on device issues discussed in first place
and not on the person who happends to write it.

For my part matter ended.
