I have an elderly (though 'high-spec') Compaq Presario desktop, which was 'donated ' to me by my sister! It was running Windows XP when I received it, but, to be frank, I was getting a bit fed-up with XP after 13 years, and fancied a change...
I installed 'Trusty Tahr' about a month ago, and wondered why I hadn't tried Ubuntu sooner! Easiest install I've ever performed, AND the quickest (I think about 22 mins from start to finish). And everything WORKS...perfectly. I had a bit of fun setting my Epson printer up, but found a way round it; see my thread here for further info:- http://ubuntuforums.org/showthread.php?t=2231123
I've since installed Lubuntu in a dual boot configuration....and that, too, went VERY nicely, and ALSO works perfectly.
The PC has been considerably upgraded since I received it, though I'm limited to 4 Gb of RAM by virtue of the motherboard using DDR1 (!).....and it's running the brilliant AMD Athlon64 (the first commercially successful 64-bit processor, from way back in 2004!) The monitor was a freebie from my bro, and I've purchased the keyboard and printer myself ( I already had them before starting). I did splash out on Logitech's excellent T400 ZoneTouch mouse; best darn mouse I've ever used, in fact...and even the 'sideways' scrolling works 'out-of-the-box'!! Under XP, it required their SetPoint software to work, and at 80 MB+, that's a hefty program for a single function to work!
So, total cost of the entire system as it is now, comes to about £40 GBP; pretty good for a system that does everything I want it to do, and has some of the best community support I've ever come across. Microsoft, you could learn a thing or two from these guys; and everybody's so darn nice about helping others out!
Keep up the good work, guys; Ubuntu is a 'keeper'. I shan't be looking to change again!
Well done.....NICE one.
Have since installed Kubuntu, Xubuntu, Mint 17 AND Zorin; all, without exception, very straight-forward and no hassle.
