over the years I've literally worked on thousands of machines, PC's, laptops, servers.
whenever I see a Celeron sticker my heart sinks because I know I'm in for a wait.
wait to boot, wait to login, wait to start application X, wait to change setting X, wait to do ANYTING
Celerons with SSD's are marginally better but still (to me) unacceptably slow.
Celeron's are "built down to a price".
They have less cache, less clock speed, less power consumption, less PRICE.
They remind me of kit cars.
From a distance it looks like a 911 GT2.
But when you start it, you realise it has a Beatle motor.
With a single carburetter.
From 1965.
