If you use your computer for doing presentations in Power Point or something like that I wouldn't recommend switching to Linux but if you are like me and basically use your computer to listen to mp3s, talk on AIM with your friends, surf the web with Netscape, and the occasional programming you may want to consider the switch to Linux. Most people will say that there is not a lot of software out there for Linux but this is simply not true. A great deal of software is available for Linux that basically lets you do anything on your computer that you would do with Windows 9x.
If you do then Linux isn't really for you. Linux was designed as a very powerful text based operating system. Companies such as Red Hat are trying to make Linux more user friendly with projects such as the GNOME project but as of yet Linux is still far harder to use than Windows 9x. In Windows 9x you gain easy of use and PnP but lose crash protection and speed (in Windows NT the speed is more relevant because it is considerably slower than Windows 9x let alone Linux). You must always make a sacrifice, which one you chose is up to you.
If so then forget Linux. Linux is for all intents and purposes a programmer's operating system. While there are games available for Linux, there are no where near as many games for Linux as there are for Windows 9x. A good solution would be to setup a dual boot using LILO (Linux Loader) with Windows 9x and simply reboot into Windows 9x when you wish to play a game.
Who does? That is the great thing about Linux. 99% of the software made for Linux is totally free and, unlike in Windows 9x where free software is usually of lower quality than software that costs money, the free software in Linux is very professional and very good. If you don't like to pirate software and hate to pay huge bills for software, Linux is the operating system for you.
If you're not an advanced user I would not ever recommend using Linux. It's a very complicated operating system and an understanding of Windows 9x and dos really helps when you migrate to Linux. If you have the initiative to read a lot about how to use Linux then Linux is the operating system for you. That is a very good thing about Linux, there are tons of books about how to use it and most of them are pretty good.
No one has ever accused Windows 9x of being powerful or reliable (or fast on sub-Pentium computers). Linux is an extremely powerful operating system, most people say that it is more powerful than Windows NT. It allows you to have much more control over your computer than Windows 9x does. However, control is not always good, in Linux it is pretty easy to mess up your computer if you don't know what you are doing. Even I have messed up my Linux box a few times and have had no idea how to fix it (usually by doing really stupid things that I know I shouldn't be doing). Windows 9x crashes a lot for most people. People just accept this realizing that there is nothing better. Well those people are wrong. Linux machines do not go down often because of Linux's protected preemptive multitasking. Microsoft did this in Windows NT and Windows NT is far more stable than Windows 9x but some people say that Windows NT still doesn't touch Linux in reliability.
No not at all. I don't use Linux regularly because frankly I don't need it. I used Linux as my primary operating system for a few weeks and loved it but I just decided that Windows 98 is better for what I do. Even though I use Windows 98, I still acknowledge that Linux is a modern operating system designed correctly from the beginning and Windows 98 is not. Windows NT tries to be but it is too slow for my tastes. I like my computer to be quick and reliable and I haven't had as many problems with Windows 98 as some of the people at the forums have had so I use Windows 98. But I guarantee if I start getting problems with Windows 98, I'll switch to Linux without a second thought, not Windows NT because it is too slow.
