HI all, Been trawling through the posts here for ages whilst deciding whether to try to make the leap from Windows to OS X and in the end I ordered the new rMBP (2.9/16gb/512gb). It arrived last night and I'm really impressed with it, despite the fact that OS X is fairly alien to me and some of the buttons re in the 'wrong' place First of all, I haven't noticed any issues with the screen juddering, although I'm not exactly sure what I'm looking for, but everything seems super smooth. Secondly, I've looked through a lot of posts and threads on noobs to Macs, but I wanted to know if there are any killer apps that people really thing will help with the transition from Win to OS X. Thirdly, even though I've only had a couple hours playing with it I'm loving the fact that it integrates with my iphone and ipad. It really feels like they are now all part of the same thing and I'm looking forward to how this is going to work as I learn how to do more and more things in OS X. Lastly, When I download and install programs, there doesnt seem to be an option to dump them into a folder like in windows and I'm just concerned I'm doing the Windows equivalent of installing everything onto the desktop and then creating one almighty mess for myself later. Is this the case or is a mac different in this regard? PS- Oh and it's saying I have 17h battery left!!
