I started with the Apple I and II's moved up to IIGS and the early variants of Macintosh computers, even the LISA. When I purchased my 1st computer it was an Apple IIGS, over the years I purchased a card that turned my IIGS in to a PC. It would let me "dual boot" to the IIGS OS and DOS 3.0. Its funny how I learned DOS on a Apple computer, he..he... from 1984 to 1987 I would spend hours just learning how to use the DOS side of my Apple. I installed DOS versions from 3.0 to 6.2.2, and then jumped from my Apple to a PC. Windows 3.0 and 3.11 was so cool to work on at them time, I also learned from Windows 3.0 to Windows 95, 98, NT, 2000, ME, XP, 2003. I have HAD enough of all the blue screens of DEATH thru the years and all the virus, spyware, malware you name it ware that would take over my PC. I would go to great lengths to just preempt an attack that could and might happen.
About 6 months ago I heard of Ubuntu, I order two books and Ubuntu and downloaded the Live CD 6.06LTS install. I had an extra can sitting around not doing anything and so popped the CD in and played around with the live cd boot up. In mid December I had Ubuntu installed on my P3 933Mhz, 512MB RAM and a GFroce Ti4200 128 RAM system and its was FAST. (FASTER in boot up and day to day tasked them my Windows XP SP2, P4 2.4Ghz, 1GB RAM, ATI 9800PRO XT system). Just recently my WinXP can did a zit-pop ~~ smoke and thank goodness I had my Linux can up and running.
The biggest problem I had with Ubuntu was installing my HP OfficeJet k60 printer. But with a lot of help from the Ubuntu Forums I was able to get the driver installed. Then the noob took over and reinstalled a different driver and that killed my k60. I looked and looked and found how to display drivers that loaded when the system stared and once I did that and re-installed the HPLIP drivers and my printer was printing again.
Ubuntu has opened my eyes to much better way to use a computer!
