First, a pre-emptive TLDR; would you recommend upgrading a 2010 MBP or buying a new 13" rMBP? ~~~ Second, the too long portion My current computer is a 2.4GHz 13" MacBook Pro from 2010. With a 256GB Crucial M4 SSD and the original 4GB RAM, it's more than powerful enough to do all the things I currently need a computer for: Web Development (BBEdit and Acorn) LEGO LDraw modelling (Bricksmith) Podcast Recording & Editing (Skype Call Recorder and GarageBand, 50GB) Comic Book Library (7GB) iPhoto Library (8,000+ photos, 43GB) iTunes Library (35GB Audio on internal drive, 200GB Video on external drive) However, there are three areas in which it's currently lacking: 256GB SSD is constantly full. 5GB free right now, but it was down to 300MB yesterday :O "Service Battery" warning started appearing recently, it currently lasts ~3 hours 4GB RAM runs low when using Windows 7 virtual machine, things get choppy So, I contemplate the following three upgrades: 960GB Crucial M500 SSD, 554€ New Battery, 129€ 8GB RAM, 66€ Which comes to 749€, which leads me to consider; should I spend that much upgrading this machine? Or should I put it towards a brand new one? The Mac's display is an important factor in my decision. I use an 11" MacBook Air plugged into a Thunderbolt display at work and HiDPI 1280x720 at 109ppi is amazing at 30" distance. However, the built-in 1366x768 display at 135ppi is too dense for me to use long term, the same is true of the 13" MacBook Air's 1440x900 at 128ppi. I've been using a 113ppi 13" 1280x800 display since 2006 and am comfortable with it, the 13" Retina MacBook Pro's 226ppi HiDPI 1280x800 should work just as well, with additional Control-Scroll smoothness when I zoom in. Two options I see for a new Mac are: 13" MBP (2.5GHz i5, 8GB RAM, 960GB SSD), 1819€ (1199+66+554) 13" rMBP (2.6GHz i5, 8GB RAM, 768GB SSD), 2399€ Discounting the 749€, that's 1070€ for the MBP and 1650€ for the rMBP, though the rMBP has a 192GB smaller SSD. Finally, I originally bought the MBP in April 2010, intending for it to last me 10 years. As I say, other than the three issues above, the CPU, GPU, feel and quietness of the machine all continue to satisfy me. Finally finally, I lean toward upgrading my current machine as that will still be at least 1070€ cheaper than the alternative. ~~~ And so, after all that, please do tell me what you think!
