Depends on your application; people using them for video or audio applications use Mac, business some prefer PC.
I would get a Mac, after using both.
I would get a mac because they are way better. I have a macbook and my mom has a dell xps. she always complains and I never do. Once again, it is better to get a mac.
No, of course. They're completely different brands. A Mac is made by Apple, and a Dell is made by Dell.
Dell is a PC
You cannot get your Dell computer to have a Mac toolbar legally.
i would say probably mac but dell is cheaper
Dell gives you a longer warranty than Mac does. Dell offers a 3 year warranty. Mac only offers a 1 year warranty. Dell's warranty covers alot more than Mac's warranty.
no but both a Windows and PC and a Mac can share their Internet connection. If the G4 does not have a wireless Airport connection then the Ethernet cable can be used. (See links below)
Usually Dell has good products. I don't know for sure though. I would recommend a mac though.
A Dell router using standard settings will work with a Mac. If there is a wireless network already established then the Mac should be able to connect to that.
You should be able to connect the Dell speakers to the Mac Mini and expect them to play without any problems. Occasionally, certain inputs do not match, and in this case, you would need to purchase a connector.
The battery life of a Mac and Dell cannot be directly compared, as they depend completely on the model. There are models of each brand that have battery lives that would be better than the other brand's.
GarageBand is only for Mac.
