Compare Option 3G GT Max from Cingular and 801.11 a/b/c

Compare Option 3G GT Max from Cingular and 801.11 a/b/c
1. Is the 3G better than 801.11 or does it work just as well?

2. I am able to connect wireless at home and at school. What effects would the installation of the 3G have on my these existing wireless connections?

3. My purpose of wanting to add the 3G option to my system is to have internet access on the road. Does It worth the hassle?? I know it is a little too late to ask since I already purchased the laptop card from cingular.

4. Upon installation, what should I be on the look out for??

Thanks,
Dan
