I'm currently using an old plastic MacBook (Core Duo, 2.0 GHz, 2GB RAM, Snow Leopard) that I bought exactly 7 years ago, in 2006. Still today it works pretty good for my everyday computing needs (web, Excel/Word, some writing, a bit of basic programming (learning), video streaming and iTunes). However, the laptop gets a bit slow once I have 10+ tabs open in Safari and have a few other apps open at the same time; also there are apps that I can't use because they're not developed/updated for 32-bit architecture anymore. Other than that, I'm pretty ok with it. I have been thinking to upgrade for a while and had decided to buy 13" MBA. Last week Apple refreshed their rMBP line which changed things a bit. With education discount (in UK), MBA and rMBP would each cost almost the same (the prices include Apple Care): 13" MBA (1.3 GHz, 8GB RAM, 256GB) for £1087 ($1746) 13" rMBP (2.4GHz, 8GB RAM, 256GB) for £1122 ($1802) The difference in price is ridiculously small. (£35/$56) rMBP has a better screen, better graphics card and a faster processor. Yet, I find it heard to decide which one to buy. I prefer the shape and the lightness of MBA, but also feel that I would be a fool if I didn't buy rMBP. Because it's essentially the same price as MBA and has much better specs. What holds me back from buying rMBP is the following: 1) If I can get by with my current 7 year-old laptop I don't really need the power of rMBP. MBA would be sufficient for my everyday computing needs. I'm concerned that there is a trade-off between getting better specs and un-repairability of rMBP. 2) rMBP is not user repairable - this is my biggest gripe. The battery is glued to internal components, headphone jack integrated with motherboard and so on, and once Apple care runs out, reparing it can cost a lot of money. That would not be good, especially for someone like me who is content with keeping a laptop until it becomes noticeably outdated and starts to underperform on everyday tasks in a tangible way. 3) The difference in screens (the main advantage of rMBP) is, from what I gather, negligible. I don't perceive my current screen very pixelated (or not sharp enough) and don't do photo editing, design work etc. where retina advantages might be noticeable. MBA screen is better than my current one, but not as good as the retina - but probably is good enough for what I need. 4) I'm concerned about image retention issues and potential laggy system animations (e.g., mission control) with retina display that have cropped up on forums. It would negate it's main advantage over the MBA if there is a good chance I will have it. Maybe you have comments on any of the points or in general as to which one you would think I should buy. Are my concerns about non-repairability grounded? What about potential issues with retina screen? Am I fool not to buy rMBP?
