Hi guys, I'm currently on a Mid-11 13" MBA. I bought it in 2012 to replace my 5 year old 15" MacBook Pro. The MBA I'm using is the base 13" model, 1.7GHz, 4GB RAM and 128 GB SSD. I will probably upgrade to the 13" rMBP or the rumored 12" rMBA during this summer, rMBP being the more likely choice as of now (although it may change when I've actually seen the new MBA...) The MBA has been the best computer I've ever owned, hands down. It's been ultra-silent. Most of the time, I hardly hear it at all. It also stays really cool. Last but not least, the SSD is a game-changer, hence why I much prefer working on my MBA rather than my iMac in most cases. However, times are changing and I'm really interested in having a retina laptop, seeing as I do A LOT of writing/reading on my MBA at Uni. Moreover, I would like more storage and ram, hence why I think that the rMBP 2.4GHz, 8GB RAM, 256GB SSD could be the way to go, unless Apple brings out something amazing with the new MBA. For those of you who have switched from the MBA to the rMBP (13")... * Does the rMBP run as quiet as the MBA? Reason I ask is the 28W processor in the rMBP. * Does the rMBP run as cool as the MBA? I've heard that it may actually run cooler thanks to the new cooling system - is this correct, or just marketing nonsense? * Does anyone know how the battery-life of the 2011 13" MBA compares to the 13" rMBP? Apple claims 7 hours for my 2011 MBA, but I've managed to squeeze out nearly 10 hours of this little guy, while not using Wi-Fi or BT and keeping the brightness set very, very low, normally I get around 7 hours however. How does the rMBP compare in real life usage? Other than that, how did you experience the transition from the MBA to the rMBP? I get that the Retina Display is the main difference, which is one of the main reasons for upgrading.
