I had just purchased the 2017 nTB 13" Macbook Pro and looking to return and pay the extra $400 to get the just released 2019 Macbook Pro 2.4GHz Quad-Core Processor with Turbo Boost up to 4.1GHz. Use it extensively for work but word processing, surfing etc. and nothing heavy duty like gaming, or video editing. Not a big fan of the Touch bar as well. Wondering if its worth the $400 difference to get the extra speed bump/keyboard and if so would I see a noticeable difference..
