Original HD going bad. Battery doesn't hold charge long. Memory was at min. i had contemplated on replacing above and due to experience with PC based laptops.
Got the 500g SSD Hybrid, Fast easy install.
Replaced battery and works as original battery.
Memory upgraded to 8gb.
I'm glad the i went ahead and did the replacements of above items. It's well worth the expense and runs as it originally did, fast. Advice, upgrade what you can if you can afford to. Mac products last longer than PC and well worth the expense. Only took me 30-45 min to complete upgrade/replacement.
