I have spent a full month using Ubuntu. I have two computers here side by side. One on Windows XP and the other on Ubuntu. For the moment, day to day, I prefer using the Ubuntu machine because it has the desktop option. I have my apps(ie: preferred programs) spread over three desktops on Ubuntu and it is so easy to go where you want to go today, Mr Gates.
But it has been hard to get used to Ubuntu and learn its ways. I am still very ignorant so I would not recommend Ubuntu unless you are willing to do your homework. It is still a geeky project to set up and run -- but anyone can use it. So I would have preferred it that I could call on a local Linux pro to tweak my setup and maybe install it. and thereafter mentor me in the exercise. But Linux pros are rare...(although I nagging my son to consider that career option).
Ubuntu is very demanding on your IT skills or lack there of. However, Ubuntu is great for keeping old computers alive and revitalising rejected ones.With a router ( a sort of computer mixer and sharer)it was a simply plug and play business to network the computers here. So for everyday use -- consider Ubuntu. The specialist computer user may want to be a bit more cautious, but for me, multimedia on Ubuntu can only get better.
So what does that all mean? It means I'd junk Windows today if I didn't need one program -- Sonic Stage -- that won't run on Ubuntu and requires Windows. So I keep two computers running and the one using Ubuntu was a decrepit machine that had passed its use by date while running Windows XP. Now it has a new lease on IT life.
With the purchase of a router the other tech advance kicks in here and we now have a VoIP access via an engen VioIP Linksys router box as we now run all our phone calls through the computer. There's a price to pay -- some calls can be rough -- but there's not a price to pay as running this setup costs me only $9.50 per month -- compared to $40 line rental from Optus for a standard phone line. And all local and interstate calls are a flat 10 cents. Of course this setup depends on the line being open and the modem "on" --- and won't work in a blackout -- but what do you want for 10 cents?
