Hi, I am an IT professional and use my MacBook Pro almost 16hrs in a day - at work, home and when traveling. I primarily use my macbook for heavy browsing, streaming videos, downloads, iTunes, Windows 7 on VMWare which is used primarily for MS Office & Outlook, Photoshop, aperture for editing my pictures. I currently have the 2010 model of the 13'' MacBook Pro 2.4GHz with 8GB RAM. I am now considering an upgrade primarily for 2 reasons: -- Faster processor available in the base 13'' models -- I want to upgrade my HDD to SSD and there is no option to get an Apple SSD unless I do it at the time or order. It's important for my SSD to support Trim, which I heard is not supported in non-Apple SSDs even with Lion I am hoping to get about $900 for my old MB Pro on eBay. Here are the options I am considering in the 2011 models: 1. 13'' 2.3GHz with 8GB RAM & 256GB SSD 2. 13'' 2.7GHz with 8GB RAM & 128GB SSD 3. 15'' 2.0GHz with 8GB RAM & standard HDD For my use, which of these models make most sense and will I see a significant increase in performance in upgrading my current model to any one of these, and assuming that's a yes, does the price difference between these 3 models justify itself? Will I see a significant difference in response times between the 3 models above? Specifically, I want to know if its better to get a i5 with 256GB SSD or a i7 with 128GB SSD, and does the i7 truly show the increase in performance for my use? Thanks a ton!!
