Hi,
At my place we have 2 computers, a desktop which my wife uses, and my notebook. I have my notebook on wireless. Im approaching the 30 gig memory in my laptop and want to setup a file directory on the desktop. I tried this last night for about 10 gig of streaming video i have and it took forever to transfer...How can i speed this process up? Also, would i be smarter to buy a old cheap desktop off ebay, load the hd up and use that?

Thanks
