Hello, I would like to hear someone else's opinion who has more experience. I have been happily using my Macbook Air 13" (Late 2010) but in the last year (especially after installing Yosemite) it has dramatically slowed down (which is expected for a computer of this age with only 2GB RAM, I guess). I have been patient but the "speed" is so slow that I can run only a few tabs in Safari and when I open more apps like Skype, Mailbox and Evernote at the same time, it is almost unusable as I have to wait for couple of seconds to even switch between apps sometimes. Not to mention heavier usage which really makes mu furious sometime. The main problem I have noticed is a lack of RAM so I decided to shop around for a replacement. As it is my main workstation and I spend more than 8 hours a day on it, I do not mind paying more for quality which will last longer. I have a budget about 1800 USD ready. I love the Air for its portability and even after using it for 5 years, it has been a pleasure to open such a beautiful piece of hardware every day. So my question is - Should I buy a Retina MacBook Pro 13" or should I wait for Retina MacBook Air 12"? To be honest, laptop is laying on my table most of the time in the office so Pro would not be a problem in that case. But I travel from time to time and I carry only light and small backpack with me so Air is beautifuly thin and light for that matter and I also prefer the low front lip for long typing stints. Pro is just heavier and bulkier machine with less battery life (at least in my opinion after using Air daily for years). I know there is a beautiful Retina in Pro which is a significant advantage but since there is going to be an Air Retina soon (hopefully), this would be my ideal Macbook. Yet, I still can not decided. Why? Because of PERFORMANCE. As I know that low RAM could be a real limitation to everyday us, I would go with the maximum RAM possible and I would purchase Pro with 16GB. I don't do anything graphically demanding whatsoever but I remember doing some photo and video editing couple of years ago when my Air was able to handle it. And I am pretty sure once I have solid hardware I might do some Lightroom and iMovie stuff again. Simply said I would go with 16GB RAM because I do not want to experience any lag for at least next few years in anything I do. When I have been on my brothers iMac a few times I had a chance to check ActivityMonitor RAM usage. I am running some big gDocs and idealy a lot of other small apps for fast multitasking and I am not sure if 8GB will be enough. See the print screen below. I need to run simultaneously: Mailbox Mail App Safari or Chrome (10+ tabs) including various web apps, large gDocs and Facebook etc. Evernote Wunderlist Skype iMessage Spotify Calendar Excel + small apps in menu bar such as CloudApp, F.lux, Monospan, Caffeinne, Dropbox etc. ++ I use VPS almost every day and I would need to virtualize some Win apps soon Do you please think that new Air would be able to handle all this smoothly for next 2 or 3 years? I am pretty sure if they lunch Retina Air, it will be with max 8GB RAM. And if there would be an option to purchase Retina Air with 16GB RAM I would have no doubts we have a winner here. Because less ports and CPU is not an issue in my case. There is also another thing - its a real pain to use my 2010 Air everyday so I would ideally purchase something tomorrow but do not want to make a mistake when buying a Pro soon and seeing next MBA Retina coming in a month. If I decide to wait till spring WWDC and they lunch Air Retina with just 8GB RAM it would be the best to wait for the next Pro generation, which is likely coming this summer (has not changed much from 2013 so buying Pro now in 2015 is like buying almost a two years old model, right?). Which would mean having a new Macbook in summer/autumn and suffering with 2010 Air for another half year. I dont know how to decide so please let me know your input on the situation. Thank you!
