i use vmware workstation and within there you can config the sort of connection your virtual machine had to the internet you can simply bridge your network adapter, and if you do not like that being bridged. vmware workstation has a build in nat server (not that its make much difference)
i use a vm ware to test software from publisher that are not trusted even to run games that are not 100% legit
if the vmware goes down you can simply delete the current vm and install a new one
if you dual boot you kinda have a lot more work on your hands
and if you have 16gb ram you have no problem making a win 7 vmware
win 7 requires 1gb ram at least i advice to use 2 at least just that it kinda fluent in use (best 4gb or more)
i also use dual boot on my lap top one part is win 7 to run all that software that i might need and the other part is BackTrack 5 ( a linux distro )
mainly i use the BT5 on my laptop as main OS version and win 7 is my second os (hardly use it but just incase)
i strongly advice you not to dual boot 2 windows distro's its kinda like making 2 user acc's for your pc 1 admin and 1 regular user
you will always log in to the admin because you get all options in there.
same goes for 2 linux distro's next to each other (you can easly get all the tools that make the other os appealing)
awnser to the guy that said that you need to be an advanced linux user to use linux, that is not true
ubunto and fedora are made so user friendly its kinda an out of the box distro just like windows. i kinda prefer linux above windows just the gamer inside me is the only thing inside me that is holding on to windows. (thanks to win vista)
if you know some about linux than you can do amazing stuff, if you never have use any linux distro you can't judge it
