My 2009 Macbook Pro needs a new battery and has slowed down over the years even while using disk utility frequently. I have been reading threads and debating on upgrading this to a SSD and new battery or just replacing with a newer model. I am not a heavy user as mainly just web and Office stuff with some use of Itunes. Really need to go to a Best Buy and try a new one out to see if the speed difference is that evident. Has anyone else been in a similar situation and how did it turn out?
