Long time Mac Rumors Member Reader (lost my login). Anyways, I just wanted to get some opinions. Basically, my main computer right now is a 2011 i5 Macbook Air 13'' I got it as soon as it was released. This computer pretty much replaced my older Unibody MacBook but the only thing is I have a lot of legacy stuff on my old Macbook that I can't just ignore so I do still use this older Unibody. I've upgraded this Unibody almost to the Max, except in the HD Department. Specs Currently sitting at: 2.4 Ghz Unibody Macbook 13'' (Late 2008) 8GB Ram 500 GB HD 7200 RPM Would it be worth it to drop down $500+ or more for a 512GB SSD to replace that 7200RPM one or is it not worth it anymore to upgrade this 3+ year old machine. I've been eyeing on completely maxing out this machine but as it grows older I'm not sure if its worth it. Thoughts? I do a lot of various tasks with the older Macbook thats why I have it as maxed out as possible. My friend is also offering to sell me one of his older 512GB SSD's from 2009 for a good price (Brand New). Thanks for any opinions!
