I have finally decided to take the Mac plunge. I am going with the 15.4 anti-glare for sure. I wanted a 13 inch, but screen and processor options have steered me to the 15. I have been set on getting the i5 w/ 500gb, but am now questioning it. I will need to run Paralells to run Windows on a daily basis to run programs for work. Would getting the i7 be a huge benefit here? I am a little gun-shy on cost, which is where the hesitation is. That being said, I can pull the trigger if the performance is worth it. I will be using this as a business and personal laptop. Essentially, business run on Windows and OSx for personal use. Aside from the Windows programs the device will mainly be used for the Internet, multi-media, and heavy photo storage/album creation. I believe I would keep this around 3 years before looking to upgrade again. I was hoping to hold out for a refurb, but think I am going to pull the trigger at Apple on Monday. I have researched some other places to buy, but am not sure if I will go that route or not. I appreciate any advice I can get. Thanks in advance for the help.
