Hi I brought a Mac Air earlier 2014 and I like it, its light and easy to carry around and its very reliable, so if I buy I think I would buy Macbook again, I am thinking if I should get a new Macbook at the moment, but I do not like screen getting bigger and bigger because I carry it around nearly on daily basis. The problem I have with the current MacAir is the battery about half as long as its new, its getting slower and slower and its dies more often.
I am not sure if its worthwhile to replace battery and get it checked for performance slower down. If I take to Apple I wonder if they would charge me for performance slower down checks for free or if they would charge me. I remember the recent post of the guy who got full refund for his TV after 4.5 years of usage, but I dont really want to pick up a fight.
I use computer main for internet surfing and sometime Microsoft Office.
I wonder how often you change your computer
Desktop: Every 6-7 years
Laptop: Every 6-7 years
Work laptop: Every 3-4 years
