Hi all, I've been in and out of my local Apple store 4 times in 4 days. When I've asked what to recommend between MBA and MBP I've gotten a 2/2 split. I need some help on here clearing things up for me. Here's my debate: 13" MacBook Air 1.8 GHz Dual-Core i7, 256GB SSD, 4GB memory [OR] 15" MacBook Pro 2.2 GHz Quad-Core i7, 500GB HD, 4GB memory Here's what I plan on using the chosen device for: Operating 12-15 1MB rich, macro-enabled MS Excel spreadsheets via Parallels Desktop simultaneously, ~100GB of iTunes music, ~30GB of iPhoto pictures, and Apple TV. I plan on configuring 3-4 user accounts on it, each relatively customized. Here's what I don't plan on using the chosen device for: Hardcore video-editing, gaming, anything requiring intensive graphics, photoshop, or Garageband. Here's what I need help with: Does the read/write quickness of the SSD trump the horsepower of the Quad-Core i7 when it comes to doing heavy spreadsheet design, data lifting, sifting through a large iTunes library responsively, and quickly booting multiple Parallels Desktop windows? Or does the raw power of the Quad-Core make sense despite the conventional hard drive? Please advise. I welcome any/all advice as I've been swinging back and forth depending on the day.
