Easy way is simply network them and move files across the network. Depending on the total size of the files you can use a usb flash drive, insert into laptop copy files to usb drive, safely remove icon, insert into pc copy files from the usb drive to the pc The size of the files would determine the size of usb thumb drive to buy, but they are very inexpensive and can be bought anywhere including walmart and bigots, I have several from there. If laptop has dvd you can copy to disks also, lots of ways to go.

Where is it gonna find all the laptop drivers. What will they do when it tries to use the same windows registration online.

I use RealVNC to communicate with a home server where I have some housewide apps and network storage. It's what's called a "headless" operation, meaning the PC is running but it has no monitor connected to it. RealVNC provides a capability like any remote access software, no different than what happens if you've ever gotten remote tech support. When you connect to that PC, you have a window with that PCs display, and your keyboard and mouse (or touchpad) provide input to that other PC. There's a time lag for operations and screen refresh when using it. I'd say it's best suited for what I think of as server operations, not for normal use. You certainly could use it for simple programs, etc., Sound doesn't come across, just the screen image. You wouldn't use it for games or watching video, because of the lack of sound and slow screen refresh times. My server is the central place for all files - photos, video, data files, etc. The network storage is accessible from all PCs and all local programs, so the remote access is simply to more easily setup and manipulate what's there. It works across your home network, the internet is not involved. It's free, try it, see if it does what you're looking for.

The short answer is it can be done but it may be a bit complicated. Just connecting the TV and PC via a network cable doesn't make a network. You'll have to create an "ad hoc" network to get the computer to talk to the TV (and visa versa). Reading the manual, it appears your TV can do that. Once you get the TV and PC connected, you'll need some way to stream your content. LG offers a free copy of Nero Media Home to do that. I don't know if you will be able to "share" you 3G dongle so that the TV can access the Internet. As an aside here, I don't know how much data you get with your 3G plan but streaming videos tends to use a lot of data. So you'll want to review your limits.
