I wouldn't go with mcafee or norton, try and find a good personal firewall on the internet. You do get what you pay for. If you are not worried about what people might find on your pc then there is no point getting a firewall. That is my theory.
As far as I was aware, intel have made core 2's for laptops, or are making them, so I would wait till laptops are available with core 2's and get one of those. Also, i prefer fnw over alienware. I don't know if the alienware if dual core or not, if it isn't then fnw is the way to go :P
yes, that is the flash game you are using from another website, it is not actually hosting the game down your end, but simply acts as a kind of relay, taking bandwidth from the source with no source of profit. You cannot actually host your own game.
doing news scripts can be hard or easy. If you want to make it difficult for you to update news items but easier to code, just hard code the news items using html. If you want it harder to code (if you don't know php) but want it easier to insert stuff, learn php and you can make a program for updating news.
if you wann a start making a game like runescape you need to learn java, but that takes a long time and is not an easy language, but it is the best one to start on programming wise.
or if you have a decent sound card, head to the recording section as previously mentioned, but check the "what you hear" box, that'll record the music you are listening to.
