In lieu of the new upgrades to the MBP line, I'm wanting to get an idea of how good this machine still is. I currently have a MBP 15 late 2013 model with the 256GB SSD and 8GB RAM configuration, 2.0Ghz processor. I purchased it from the refurbished store last year and I think I only paid around $1,300 for it, it was a pretty good price. From my understanding the Mid 2014 upgrade was negligible at best with only a slight processor bump and the 2015 only received a faster SSD, processor, and force touch trackpad? Other then that, I believe the processor line and IGPU was all the same correct? I pretty much use this machine as a desktop replacement. It rarely leaves my desk except occasionally to take it to the kitchen table or other parts of the house. I have a mouse hooked up to it most the time, and I only use it for basic computing tasks such as internet, word processing, storing files and documents, and streaming media. There are also times where I just prefer sitting and using a 15" screen instead of my smartphone... I'm jut wondering how long it will last, I have 109 battery cycles on it, wondering when I'll need to change the battery or when the software starts passing the hardware. I know Haswell processors are very good and this model is largely unchanged even from the 2015 version. I've thought about looking into Windows laptops but I just cannot even come close to finding one that matches the fit and finish and quality of a MBP. The only one that I even remotely getting close is the Dell XPS but I've heard it has its own array of issues as well. I typically review this once a year when Apple releases new laptops. As we move more into a mobile market I'm using my computer less and less, but I still can't bring myself to switch to iOS only. I still feel like I have to have a computer to store all my information and times where a computer is truly needed compared to a phone or tablet.
