They're too good.. for their own good
Trouble is, and I know the Reg has stated this themselves, PCs are just too good. Same goes for mobile computing really.
I looked at upgrading my 4 yr old PC with an equivalent model (i7, 16GB RAM, SSD, decent video card, etc) and found today's models benchmark maybe 10-15% faster than my own.
As my current machine boots up from POST to everything loaded in the system tray in under 2 minutes, it's difficult to justify the $1000+ required to purchase something better. Worse.. new games still run at decent settings at over 60 FPS. Not max settings for sure, but I don't have to move the performance "sliders" too much to the left. Photoshop and Premier still tick along at excellent speeds, 3D Studio churns out awful attempts at rendering at a brisk pace. Simply put, stuff today is too good.
Same goes for tablets and phones. Swap out the battery and if it isn't over 3 years old the chances are it will run the latest version of your mobile OS at a very respectable speed.
Moral of the story. Make sh!!tter stuff guys.
