So you subscribe to the theory that every customer that doesn't complain
to the manufacturer about a specific problem is happy?

If only 0.1% told the manufacturer that they were happy would that mean
that 99.9% are unhappy?

The bumper/case solves the problem and that's great. But to claim that
other handsets have the same problem is ludicrous.

Good article that may help nospam understand is at

Marketing trumps engineering concerns at many companies. The antenna
engineer was spot-on in explaining to management the issues with the
external antenna, which as all antenna experts have stated were very
obvious. How the story leaked out is another story, it should not have
left the confines of the company.

I've warned customers of problems with their seemingly clever designs.
Thermal, EMI, and antenna issues are almost always the most difficult
issues in the design of a portable electronics product because there are
so many conflicting requirements. You need cooling but you don't want
openings for air flow and you don't want fans and you don't want
expensive heat pipes. You need the antenna to work but you don't want
any other EMI. The thermal and antenna issues need to be considered with
the product held in different orientations. I had a customer that wanted
a fanless system that would operate horizontally or vertically with
almost no venting. They designed an enclosure without considering the
chimney effect, so in one orientation the product would overheat and
thermal management firmware would reduce the CPU speed to reduce the heat.

I know what you meant, but that's not what you said. It's important to
not imply that just because only 0.5% of customers complain that the
other 99.5% are perfectly happy--it doesn't work that way.

"It is estimated that for every customer complaint received, there are
at least 26 complaints that are never expressed. ... Furthermore, a
customer with a complaint is likely to tell 20-25 other customers and
potential customers about his complaint.

I just tested my Motorola RAZR V3m. I'm sitting at my computer in a
room in the second story of my house. I have three, out of a possible
four bars in my signal strength display. I can touch any part of the
phone without affecting the signal strength display!

*Some* other handsets may have the problem but clearly it's not "all"!
