i need to replace my x series lenovo badly and have been eyeing a mac for quite some time. like many of you, i was disappointed with the retina 13's offerings but i cannot wait for haswell.
so i'm up between the macbook air 13 and the macbook retina 15. i heavily multitask and do a lot of web dev, photoshop, youtube, and other media consumption like streaming movies/live sports etc.
the retina is intriguing because of the extra screen estate. i was planning on using quickres or similar applications to unlock more screen real estate for the retina display. this is a plus imo but i understand there is a performance hit when forcing the rmbp to display unsupported resolutions
though portability is a factor (i'm coming from a 12 inch ultraportable) i find that i hardly walk around with my laptop compared when i was a student walking around campus because i now go from car -> coffee shop or car -> library. is the footprint for the 15 rmbp too much? (like for instance if i were to travel by plane would it fit on the tray?)
i don't expect to game on the laptop so the discrete gpu may be a waste but are there other benefits of having a discrete gpu other than driving the retina display?
what irks me is seeing battery benchmarks of the retina 15 (when forced to integrated) matching or even surpassing the macbook air 13.
what draws me to the macbook air 13 is the footprint and possibly thinking that the processor and ram would be sufficient for my needs. i have a desktop at home so this would not be my main computer but i'd like to be mobile as much as possible and not have to rely on my main computer for work.
help?
My thoughts as follows;
It sounds to me like you have two things you want. Power and portability.
One thing is for sure though,
doing work like photoshop and so on is not very fun on a 13' inch machine. And if color accuracy and nice pictures are important to you, then the Air won't cut it. Don't get me wrong, the Air has a fine screen, it's suitable for watching movies and all that, but. As a get-serious-work-done? I don't believe it's the right tool for advanced photoshop.
As for watching web / youtube. If you've been on a integrated GPU laptop you know how taxing Flash is. Most of us hate how it fires up the fans, kills the battery life, and is responsible for 90% on all crashes. But while we wait for HTML we can only hope that Hashwell will save us.
The footprint is not as vast as you think. The bezel on the air is actually quite large. If you are a big guy, with broad shoulders and/or big hands, you might appreciate not having to cramp yourself down in front of a smaller machine.
For me, the problem with 15-inchers was always sucky battery life(windows), weight and the form factor.
rMBP is an amazing computer because it crosses the realm of a MBP15 and an Air, but it does it without the tapered design. Meaning it feels even more durable. rMBP packs a very very fast quad-core processor, it has wonderful speakers,(for a laptop) that are so good that it beats quite a few dedicated 2.1 speakers you can buy in stores.
And then the screen.
The thing is that rMBP is the whole package, and its a pound lighter than the previous generation. This is very significant. It weighs the same as many subnotebooks (not ultrabooks!) but packs desktop replacement power, and its very thin. When typing on it, the footprint is actually appreciated. Its so thin and light that it feels like two pieces of thick aluminium glass. Foot print is not an issue anymore when the bezel is so small and the weight is so low, you can effortlessly carry it open with one hand. So its valid to use in bed. Most 15 inchers.. they are usually to heavy for your hand.
As for performance hit. Its a question mostly of optimization. When Adobe is going to release their Retina aware programs, it's going to change a lot of stuff. Resolution independent. You can view a picture in 4K resolution, even though the UI looks perfect and normal sized. This means that the tools (UI, cursor, buttons etc) are in a different resolution, than the pictures you are working with.
But you also write that you have a dedicated system at home. Which is weird because, what exactly are you going to be doing of productivity when you are away from your desktop? are you really going to do photo manipulation when not working on your main computer with its own screen at home?
rMBP is most def a desktop replacement. essentially, your paying for a powerful computer that was made to be your only computer if needed be.
Air is a supplementary computer.
its also irresponsible (IMO) to get such an expensive product like rMBP if you are not really going to use all it can. photoshop can run decently on integrated GPUs from last generation as well, and even though the MBA 11 and 13 will be hot, HD4000 can do HD Youtube and Hulu videos no problem.
But then again.. you also say that you dont even carry it around all that much. just from work to your car?? so do you really need something that is so incomprehensible light and gives tradeoffs because of it? The thing about Air and other ultrabooks is that you are paying for something that is possible to carry around your bag +10 hours a day.
TL;DR - You need to gauge what is more important to you.
If you need a bigger screen, and fast computer that can handle many apps at the same time. if you want a computer with great color accuracy, great speakers, and basically the entire package but for a very steep price, go with Retina.
If you dont really need that much power, and it just needs to do web, flash and photoshop. get a much cheaper Air.
Also, you said you cant wait for hashwell. But consider for a moment the benefits promised. much less power, theoretically twice the GPU performance, the possibility that MBA might have Retina, and one of my favorites - That all 2013 Macs might be decked out with the new wi-fi standard 802.11ac that in theory should make wifi signals 3 times as strong, if router its getting signals from, also have this new standard.
IvyBridge is fast. combined with Kepler(rMBP15) its amazing. its peanut butter with jellly on top.
How future proof do you need to be? how much SSD is important to you?
I suggest you go to an apple store. Try holding a rMBP15 for yourself and see if you find it heavy or light. Personally I think they took the best footprint possible, and made it portable. But I also think that hashwells performance upgrades, and software upgrades, and perhaps lower price(?) might just be what could make the machine near perfect.
