Here are the specs I'm looking at: - 2.93GHz Quad-Core Intel Core i7 - 8GB 1333MHz DDR3 SDRAM - 2x4GB - 256GB Solid State Drive Now, here are my questions: 1. Is there a big difference between the 4x2GB over the 2x4GB? What about the 16GB? 2. Is it wise to get a Solid State Drive? I heard that their performance diminishes as time goes on whereas an ATA drive does not have this problem. Is this true? Is the ATA 1TB better? Or is the optimal solution to get both the 1TB and Solid State Drive? 3. Now, the main 'problem' that I want to correct in transitioning from my 2GB, 2.4 GHz MacBook Pro to this iMac is SPEED, EFFICIENCY and SPACE. So, to elaborate on question 3: SPEED and EFFICIENCY: I don't want to wait several minutes to have my computer boot up. I don't want to wait a lengthy period of time to open up Safari, Word, etc. I want these to open up at the click of a button because I don't think that's an outrageous convenience to expect nowadays. I don't get that kind of performance with my current MacBook Pro. I have a tendency to have a lot of documents and Safari tabs open and even THAT slows down my MacBook Pro... so, will the configuration listed above give me the lightening fast performance I want? Or do I need the 16 GB? SPACE: I store a lot of files on my computer, archive a lot of documents and media. I think this is part of the reason my MBP runs so slowly at times... I want to be able to store a lot on my MBP without running into any slowdown. I don't want to have to worry about storage and the accumulation of stored data and how it will affect my performance. I want to be able to store a lot and still depend on the fact that when I open up Safari and have a ton of tabs, not only will Safari open up IMMEDIATELY, but the computer will continue to perform PERFECTLY even as my documents and tabs continues to grow. Will the configuration listed above allow for this? Or do I need a 1 TB HD in addition to the Solid State drive? 4. Can I use a Mac Book Pro screen as an external monitor for my iMac? Can I connect an MBP to an iMac in such a way that allows for the dragging and dropping of files across screens and computers? Anything like that? THANKS!
