Time for a New Laptop?

My laptop has started to run kind of slow and I'm starting to wonder if it has something to do with me loading things onto it lately. I'm not a geek by any means so I have no idea what is going on. It really could be that it's just getting old and is slowing down but I can't say I would know. I've been thinking it might be good to buy memory so I can see if that helps at all. I know I'm in the market to get a new laptop soon so that tax refund check couldn't come sooner but I'd really like to still use this one too. I will always love my first laptop and can't really think of using something else yet. At any rate, having more memory will help when it comes time to transfer things to the new one as well.
