Ever sence I layed eyes on Windows 7 I wanted to install it, I have the disk and everything is ready to go but I began to have second thoughts. Like what gliches,problems,bugs etc does it have? Someone at my fathers compney had problems with Windows 7 and I remeber that Chris Pirillo has USB detection issues. Plus what will happen to my preinstalled software that came with my computer (I have a sony VAIO and i like the preinstalled software). So in closing should I or Shant I?
