Memory Gap

I really want a new computer. A bright, shiny new iMac. Why? For one it's getting frustrating to have limited memory left in my laptop. It's still a pretty good ratio (free and used space) but I noticed that my MacBook is getting slower, especially when I have lots of windows or tabs opened. It also seems that when I open my windows programs it takes longer than before. Hay. Wish I had the money!

Then again, I suppose I can add some memory to my laptop?
