Hello all! Torn between a couple choices and really need help. I just purchased the iPhone 7 after not having one since the iPhone 5. I really enjoyed the Samsung notes until recently. I've also decided that I really want a MacBook. My "main laptop" is an MSI Titan, but I rarely-to-never take it out of my house as it's not really portable. The laptop I'm looking to replace is my school/work laptop. I have a Lenovo yoga, which is a gimmicky pile of crap. I just graduated last month and will be attending school in the autumn to obtain a masters degree in Urban Planning. I just landed a transit planning gig. Programs I use frequently in school and soon-to-be at work are: GIS (geographic information system) - usually ESRI/arcmap, CAD, photoshop, and stuff like that. I'm stuck between the MacBook Pro 13 and 15. I understand that the 15 has more power, but I'm more attracted to the portability of the 13. I'm stuck between the 13 with upgraded RAM and processor and the base-ish 15. I'm not really sure though. Can a base-ish 13 get what I need done? I'm not familiar with Mac products at all. Any suggestions would be helpful. Thank you.
