I have one; used it everyday until Christmas when I changed to a MacBook Air. Loved that thing (can't bring myself to get rid of it 🙄). Very happy with its day to day performance, but it has had problems with the hard drive, the keyboard and in particular, cracks developing in the casing near the trackpad (but as I said, I used it heavily). The battery wore-out around Christmas and I had to get it replaced. If you plan to keep it in the end, I recommend getting a strong outer-shell type casing, like I had.
Other than that, I imagine they're cheap and for general computing should be fine (I have 2GB RAM, runs good with that set-up), although I recommend you back up your files regularly (as with any aging computer).
Also note that without a dedicated graphics card, it struggles to do anything intensive graphically (i.e. don't buy this if you want something to play games on).
