If there's nothing actually wrong with it I'm sure you could get it running well again. I have 3 macs older than yours and they all run fine. Have you tried anything to diagnose/rectify the problems you're having? My gf's newish macs was running v slow so I told her to get Onyx and run all the maintenance/cleaning - did the trick…
Slightly pointless post, but my iMac G5 (4 years old) is about to die and i dont have the money to buy a new laptop, even with HE links
it takes fucking ages to load anything, can't stream shit and sounds like a harrier all the time. 
Also if your hard drive is full or has less than 20% free space it will run really slowly! Onyx is really good I told my Girlfriend to use it as she had a similar problem as Voltaire's Girlfriend. Also us Monolingual to get rid of language files that you don't need, you'd be surprised at how much is freed up by it! Got's lots of crap on your desktop, tidy that up so you the least amount possible on it, that also helps a little!
