LABTOP

I think my MacBook is slowly dying on me. Every once in awhile the
popup pictured above shows up and then I have to restart my computer
and then when it's rebooted it says that osx leopard has crashed. :
( i've been saving since the beginning of summer to buy a new labtop
and I'm only a couple hundred away which is exciting because if I get
the money before the 17th then I get an iPod touch :) I don't need one
but I can sure sell one on eBay. Should I rush my savings and get the
iPod touch or just wait it out.
