Really hung on this, and I've gone back and forth a number of times. I'd love to get a computer that lasts me 4-5 years. Use is not so strenuous - light photo editing, lots of PDFs and Word/Excel (and Mac equivalent) work. Sometimes 10-15 documents at once. Occasional 3D rendering but not enough (IMO) to warrant consideration. I purchased a 13" MBP w/ TouchBar (base, 8 GB of RAM, 256 SSD) along with the LG UltraFine 4K and Apple "Magic" Peripherals. Cost was 2,710.44 after tax. The alternative is a 15" MBP w/ TB (base) at a cost of $2,548.94 after tax. With a differential of only $150, which of these "bundles" will take me more into the future?
