Upgrading the core

Computers are always changing these days and have been for the last few decades. I remember my first Windows computer, a 486 processor running at 33MHz with 300Mb hard drive, which I later upgraded to a blistering 100MHz. Now PCs have up to 8 times as many processors and run at speeds up to 50 times higher with storage simply unthinkably large compared to the days of floppy discs. Heck even the CD / DVD has ceased to be what people save their transferable files onto due to cloud storage or USB keys which store many gigabytes of data. Something buddies and I were having a laugh about over a couple of beers today in fact!
