Usual Microsoft Mantra, "This new Windows XX is so good you have to buy a newer faster pc to do what you used to do on the older Windows...."
If newer software didn't keep pushing the envelope, hardware would never improve or evolve, and we'd all still be running PDP-10 machines from the 1960's.
I'm not saying that there isn't a place for eeking out the utmost useful life of existing hardware, but that place is not on the bleeding edge, latest versions.
If you want to keep doing what you've been doing on your current hardware, then keep using the software you've been using. It's simple really.
Linux user since Slackware 3.4
DISTRIB_DESCRIPTION="Ubuntu quantal (development branch)"
Linux ThinkPad-T40 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:52 UTC 2012 i686 i686 i686 GNU/Linux
Just did sudo apt-get update, sudo apt-get dist-upgrade. Mostly worked, downloaded all of quantal including 3.4.0-5 generic which requres pae, and should not have installed and didn't.
This is a Pentium M with no pae so "sudo aptitude full-upgrade" keeps trying to install 3.4.0-5 won't work, Y,n,q and the only useful choice is q. "safe upgrade" picks up changes that will work.
Anyway, running fine, recommended.
The 3.3 Ghz ATI radeon xpress 200 running fine once I figured out I had to use "nomodeset" to boot the startup disk. Shades of Intrepid for those of us that go back that far, Dapper Drake Beta for me. Some problems seem to haunt Ubuntu forever.
The widescreen notebook has mucho problems with with wide screen and especially external monitor et. al. something to do with fglrx likely, people are working on it. It'll do 64 bit I rarely try that.
This is a Thinkpad T40 fits fine on the dining room table, QQ lubuntu running responsively using precise kernel, example of a successful upgrade.
From time to time one or another of my pc's does fall off the bottom: A 2 GHz with Intel integrated graphics running too slow for me after Intrepid. A 1 GHz Thinkpad runs O.K. with Lucid rather sluggish with any Narwhal and later.
Now Microsoft is master of "new operating system with lots more overhead, buy it installed on a new faster pc".
I'm an "ordinary user", internet video, email, research health, news, weather, shopping, politics, sports activities to do... There's a whole community out there that has to have the very latest hardware gadget and the very latest software to exploit it for the fanciest eye candy and exotic games. They seem to be pretty good at finding and filing bugs.
Having fun, Jerry
Found another way to use the Pentium M non-pae with Quantal. Quantal's running on my big clunky widescreen (wide but short screen squint) notebook, and the Pentium M is on the dining room table (much better fit) running ssh -X to the clunky widescreen notebook firefox et. al.
Not sure about the video speed (you tube Shakira) I guess I could put them side by side and compare.
Still having fun.
p.s my usual fiddle with Ubuntu Hacks and The Official Notebook plus Ubuntu Wiki to get ssh running wireless security et.al. Not many commands to get it running, and not sure which ones did the work, and hopefully my neighbor's kids can't log in or view files...and most importantly my wife can still print pictures over the network...
p.p.s. Pentium M's mostly updated from precise to quantal except kernel of course and some other stuff I don't know what is used for.
