Having started in computing before CP/M and DOS the last 30 years have been exciting and forever changing. Change is inevitable and what comes out of change is mostly improvement. I would not like to be driving a Model-T on today's highways any more than I would like to be still using PC-DOS 2.01 first released on the IBM XT in 1981. Office 2010 is brilliant compared with Office 97 as was Vista compared with Windows 3.11, W7 is better than Vista.
By the way Ford did change the pedals after the Model-T.
