Hey there everyone. Just purchased my first MacBook Pro. I initially ordered the 13" MacBook Pro And was planning to upgrade the HDD and Ram but when I went to the store and seen the Retina display I caved. So I went with the 13" 2.5ghz i5 with 16gb ram and a 256gb SSD. My first experience is WOW ! This thing runs like a dream. Its so fast and smooth. Simple little things like scrolling and zooming when surfing the web is so smooth. I haven't got anywhere near testing the capabilities of this machine yet. I bought it for the sole purpose of Audio Production. So by next week I hope to be running Logic Pro X and indulging in all the fun. Right now Im just too busy with Xmas to do much with the MacBook. Im getting loads of questions but I'm sure it won't take long to effortlessly run this OS. I have a few concerns that I was hoping you guys or gals could clear up. 1. Apparently theres no way to get into the back of this Macbook if something breaks and needs to be replaced ? Is that true ? This was kind of the reason I was gunning for the 2012 Macbook but I got lost in the retina display as soon as I seen it and couldn't resist the bright colours and sharp picture quality. 2. How reliable are these computers ? Can I expect this thing to last a good few years ? I did purchase the Apple Care warranty as I furred it was worth the money considering the cost of the macbook. 3. Battery use, I am mostly going to be using this computer at my desk when recording but I went with a MacBook because I travel a lot for work so I want the portability as well. Is it OK to leave these plugged in for days to weeks at a time or should I regularly be using the battery so I don't ruin it ? Not really sure how all that works so hopefully someone can clear that up. 4. SSDS, another thins I've read about SSDS is that they can only write and re write data X amount of times. Is this something that I should be concerned about or are we talking years here ? Sorry for all the questions but I'm pretty new to a lot of this new technology. Thanks in advance for any help.
