Marketing or true speed?

Hello,

I'm very disapointed with hardware industry (ok, we can save one or another from the mass).
My first disapointment was when I acquired a Wireless adpater and router to work at home without wires crossing my room. Ok, this should be a great solution and when I saw that this solution can reach 54Mbps my smile appears!

So I bought it and install it. "Ok, let's test this baby". I have tried to transfer a huge file from my Laptop to my Desktop (both wireless). What? 6Mbps??? Yes, it is true!

But, on the hardware box is saying 54Mbps! Where are my Mbps???
So I have opened my Google window and start to search on the Internet to find out if this is a problem related to my hardware brand. Surprise! All sort of brands are being attacked by its customers about exactly the same reason!

Most advanced hardware specialists told that this is a nominal speed and, in fact, it can only be reached on a perfect environment condition! Ohhhh, companies are playing around with us?

Ok, as this is a common problem my anger was gone in a couple of weeks.

But...the story does not ends here...
My brand new acquisition, a USB 2.0 HDD external drive!
Uau, USB 2.0 runs at 480Mbits/s. UAAAAU!!!
This should run at corresponding 80Mb/s.
End of story? This is a "theorical speed"...nominal speed...on perfect conditions...blablabla!
True speed? just about 10Mb/s....

OH MY GOD!!!
I'm feeling a complete fool!
Don't you?
