When it can no longer efficiently perform the tasks you use it for on a daily basis
That will vary from user to user
Real answer: White MacBooks are getting pretty close to -needing- replaced. They are getting slow and parts wearing out.
Precisely!When it can no longer efficiently perform the tasks you use it for on a daily basis
That will vary from user to user
Most do not need the latest and greatest on a regular basis
My 2007 MBP would really perform most things for me just fine now
I upgraded to the 2011 MBA for the mobility over my 17" MBP
I wonder how long should it be considered rational to replace your macbook?
