Any informed opinions here about which memory size to choose if I want to future-proof the machine? Given that it looks like Apple is finally getting its act together with MBPs after a long while, I would like to use the new computer as long as possible. I don't do video editing or other heavy stuff. Mostly I "need" to have dozens of browser tabs, pdfs and word files simultaneously open. 8gb is clearly too little for this, as I've noted with my current machine, and the new MBPs seem to come with 16gb as default. However, I'm wondering if even that will be too little after 5-7 years of technical development. Should I go with 32gb even if it's ridiculously expensive (and I'm hardly a millionaire, but could afford it if I really want to).
