So I was interested in buying an MBA or MBP to use in a unique scenario. I want to give using OS X full-time a try, my current 24" iMac however is not compelling enough to use in place of the 30" monitor and sound system which I am accustomed to with my Windows gaming machine running a 3rd gen i5. I also currently have a ThinkPad T420 which I never use anymore since my needs to use it for school are gone and I don't really have a regular need for a portable computer. I still like the option of a portable PC as a just in case measure. This is where I thought an MBA/MBP would come in. Given Apple's non-standard lineup compared to PCs or custom built PCs, I figured one of these would give me the chance to use a KVM and use OS X on a more regular basis and still have a laptop should the need arise (I use a T430 work laptop every day in this fashion without fail). However, I have been seeing a lot of talk about MBAs having logic board failures (likely from overheating due to the small enclosure), SSD failures, hinges breaking, screen failure, and RAM failure. This leans me heavily toward the MBP route instead since it is far more user serviceable and isn't so small that it compromises its performance for mobility which ultimately while nice is not utterly necessary. My first assumption without any research was "I bet MBAs are real reliable because they have almost no moving parts" but then I read lots of stuff saying otherwise and people having issues only a little over a year or two in. My T420 is from 2011 and has given literally zero issues. It's worst "issue" is the fact the original battery instead of lasting 5-6 hours like it used to only lasts about 4 hours now. I used it as a college laptop regularly for over a year without any issue. Before that I used a huge Asus gaming laptop with no issues except the expected crappy battery life of 2 hours (Pretty good for as powerful as it was, and it never got hot). So my question is pointed towards MBAs and a little toward MBP if anyone can give me a truthful answer here. I don't need any "Mac is better than Windows" bias here, I'm open minded to Windows, Mac, and Linux. I say this mostly because when I've searched it seems like someone always says something derogatory against Windows machines. Sure the cheap Windows laptops can have issues (Although my parents are using an entry and mid-level Compaq and Dell laptop respectively and haven't had any issues), but I compare stuff like business grade Windows laptops such as Latitude/Precision, ThinkPad, and EliteBook which offer great build quality and features much like Apple but in the Windows environment - and are often discounted to entice businesses to purchase. I see new ThinkPad T430 laptops for $500 with extended warranty and they're loaded out with an i5 on the base model with 4 GB of ram - but I'm ok with the extra expense for the Apple stuff assuming it's just as trustworthy as that stuff is. The T430 of course doesn't have OS X, and I don't like Hackintoshes. From what I've read though, that's not true - and that concerns me. With laptops like the MBA has Apple compromised the longevity of the laptop by making it ultrathin which doesn't allow it to ventilate as well and thus stays hotter which wears the electronics out faster? I'm not sure a Mac Mini wouldn't work for me as well, but they aren't specced out like a 15" MBP nor are they portable which is what I'd like just for the versatility (Even if it will never leave my desk for 99% of its life). Thoughts? I have a Mid-2012 13" MBA I was considering for $600 which I was sure was a great deal but now am concerned how long it will last (And it's already past its AppleCare window).
