After years of using PCs & my HP dv3500 having many issues... I'm ready to switch to rMBP 15" Before I jump the gun though I have a few questions. I'm not too tech savvy, so please bear with me. I am a blogger and social media manager for multiple web sites. I spend anywhere from 6-12 hours at a time on my computer. My current laptop is an intel core dup CPU P7350 @ 2.00 GHz 2000 Mhz with 4.00 GB physical Memory and 8.19 GB virtual memory on a 64 bit operating system. 1. Checking out the apple store it seems like the bare bone 15" rMBP priced at $2,199 is comparable to my computer.... right? Or do I need to add anything to it? 2. I'm a little concerned about overheating. I do the majority of my work from the couch or bed, would I need to purchase a cooling mat? I heard Macs tend to overheat more than PCs & mine get's warm at times, but I keep a book under it & that normally keeps it from shutting down. 3. There are some days my computer acts like it wants to die any second & other days where it runs smoothly. If I can wait it out, do you think it's worth waiting until June for the rumored updates? Thanks!
