I have a 2011 base model 27" imac and love it. However, I have been thinking I would really enjoy the portability of a MacBook pro, combined with a large display when I am at home. I have some questions and was hoping for advice. 1. I would likely be getting the base model 13" MBP that is 2.5GHz dual-core Intel Core i5, compared to my current 2.7GHz Quad-Core Intel Core i5. I know I am giving up some horsepower there. I am not really too demanding on my processor, but I use Aperture a good bit (some brushwork), sometimes edit some HD videos ( not too often) and convert videos using HandBrake. Otherwise my computing is pretty mundane, word processing, web surfing, etc. How much will the switch hurt? Will it be excruciating or just slightly annoying? 2. I am concerned about moving from my 1TB HD in the imac to a 500GB in the MBP. Can I swap out the HD for a 1TB (or larger) unit? How hard is it to replace my ODD with a SSD? 3. As far as selling my current imac, I am about 3 days away from the end of my 1yr warranty and do not currently have AppleCare. Is Apple real sticklers for getting Apple Care bought before the 1 year expires, or if I missed it by a day or two do they cut any slack? I am thinking my resale value would increase with AC, but I know I wouldn't get ALL my money back ... I am thinking it would make it EASIER to sell though. Any thoughts would be appreciated.
