well spoken...and exactly the same words are valid for Linux. Fast, reliable and not forcing to follow each and every upgrade announcement.
It is hard to understand, at least for the ones here who use computers since years, that exactly the same work done 15 years ago needs today a racing machine with truck load of mostly unnecessary programs, slowing down the whole unit to snail pace again.
Most important when deciding for an upgrade or for the first PC, make a list of what you essentially need, than the less important stuff. Do not put the least important on a priority list the dealer likes to persuade you to see.....
