I'm interested in an iPad to take some of the workload off my 2007 MBP like email and web surfing etc. Can't afford a new MBP right now. I use it for graphic design, photo & video projects. So if I can extend the life of it, and use an iPad to fill gaps it will help for now.
I heard that every email you send knocks 1.3 seconds off the projected lifespan of the MBP. Seriously.
