My first MAC laptop was a mid 2012 13″ non retina MBP. The chunky one that they sold for many years. I believe it cost $1,100. I don’t know what the original specs were but it ended life with an old school 1 terabyte HDD and 16GB RAM. It used to eat HDD cables so I always kept a few on hand. I didn’t purchase Apple Care for this computer. I used it as my main laptop dual booting OS X and Windows. This was until I purchased my next MBP in early 2017. So, almost 5 years. I’m going to go with $1,500 / 5 years or $300 per year.
The second one was the first touchbar 13″ MBP. I also purchased AppleCare for three years. Ths one cost $2,000 and came with a 512GB ssd and 8 GB Ram. I never dual booted this machine as upgrades weren’t really a thing anymore. I’m going with $300 for AppleCare but can’t remember if this is right. Within the first year the machine was sent out for a new display as it stopped working randomly. At the end of 3 years it was sent out for keyboard issues (butterfly keyboard) and received a new battery and top case as part of fixing the problem. All off these issues were covered with the AppleCare. I still have this computer but have replaced it with a new MBP as of January 2020. So $2,300 / 3 years = $766 per year plus downtime of being sent out twice for repairs.
My third and current MBP is about one year old. I purchased it in January 2020 and it is considered a late 2019 model. I bought the base model 16″ model with an MSRP of $2400. I bought it on sale at Best Buy and paid almost $2400 with tax. I didn’t purchase Apple care. Although the keyboard design was improved it currently has one key giving me issues. It also on rare occasions panics and completely shuts down. If these types of issues persist I’ll probably get rid of it after another year. Likely cost is $2,400 / 2 or $1200 per year. Even if I get 3 years that gives $800 per year.
As I need the Mac for iOS development I’m kind of committed. I used to buy whatever Windows machine came along while never paying over $1000 per laptop. My current MBP was a huge improvement with the 16″ display so it’s not completely fair to compare these models. However, one thing is certain – My first MBP was more versatile, lasted longer, and cost less to own. These days it would be considered a brick as far as being bulky. It was still the best Mac I’ve ever owned aside from my mini’s that is.
