The main problem isn't the operating system people have trouble with.
People complain there 10 year old printer doesn't work anymore. And the driver on the cd doesn't work. They don't even know what a driver is, have no idea you can most likely download a vista driver for it.
People cry about that they can't use their favorite obscure program anymore. Let me reply to that with a question. Can you still use your favorite windows 98 program on xp? no
It's normal that programs written for another operating system don't work on another.
If you update your pentium 3, 256mb ram pc to vista you shouldn't cry about slow response.
People cry about it uses 80% of the ram all the time. They are used to xp using only 15% of the ram all the time. --> Do you find it normal that you buy a pc with 2gb ram only to ever use 20% of it at all times? The reason vista uses that much ram, is to speed up the pc. It "learns" what program you are likely to use an preloads them to give you faster access when you open it. It clears those programs from the ram, if you need your ram for other program that require lots of ram.
Some people just aren't used to change. And they don't like vista because the location of some folders have changed. Or that you have to press another button to change the background.
They ***** about virusses and spyware, and when microsoft copies parts of linux superior protection, they *****. You shouldn't be admin for day to day tasks. If you want to install an program as non admin, it should ask you if you want to install a program.
The vista operating system is cleary superior on all fronts to xp.
And i'm no microsoft fanboy, i'm just tired of people bashing vista for normal things. I use linux mint cassandra most of the time, and from time to time use vista home premium (if i'm to lazy to reboot to get into linux after someone opened vista), and find it surprisingly good.
