Um... Huawei is one of the world's largest telecommunications equipment vendors, with something like USD$12 billion in 2007 revenue.

Would you describe HP as a "calculator manufacturer"?

Not since they started making their modern non-RPN crap.

Yes, I know HP still make some RPN calculators - and I have one (+ a few older ones) but these are now second class citizens and RPN is only a "mode". Gone is the big proud ENTER key.
