You can only go as fast as your internet connection allows you. and on cable thats as fast as you can go. It doesnt matter how fast Limewire goes. It also boils down to the hosts and how much bandwidth they give you while downloading. If you are a heavy downloader then Pro might be worth it to you. Otherwise the free, basic version works just as well, if not better than Pro and you wont have to bother giving out your cred card details. but if you want to go pro then the ONLY way to get it is to go here: www.limewire.com any other place/site is a fake. Pro only costs 18.88 US dollars, and you get 6 free months of upgrades. No P2P app can promise you top speed, whether you pay for it or not. Thats just not how P2P works. You download the same files from the free Gnutella P2P network no matter what app you use and no matter what price you pay to use it.
