I started this thread because I am curious how other macbook owners feel. After a few years of having your macbook, what makes you want to buy a new macbook? If it is speed related, would you rather spend $1000-$2500 for the newest model macbook or would you rather just upgrade the hard drive to a solid state drive for like $150-$250 and get an even better boost in speed? The reason I ask this is because most people I know when they start getting frustrated that their macs are getting slower, they want to get a new macbook entirely and don't even consider the other options. I just want to know what your opinion is on the matter.
