I'm really hoping someone here who uses both Windows 7 & Mac OS X will talk me out of this. I just saw that the Refurb store has listed 2.26 Ghz Macbooks for $759. I'm really tempted to order it and sell the Samsung QX410 laptop I just bought on Black Friday. Should be able to sell the Samsung for $700 + I would be getting less computing power (Core 2 Duo vs. Core i5) and a lot less hard drive (250 gb vs. 640 gb). But I would be gaining the Mac OS, which I am really beginning to prefer. For how I use a computer (light photo editing, word processing, heavy duty spreadsheet work, internet), the Core 2 Duo will be fine and I'm using my shiny new iMac + 2 large capacity external hard drives for primary storage. A little bit of a back story -- the Samsung is what headed me back in the direction of the Mac OS. Three weeks after I bought it, it died. Samsung's crappy customer service left me without a laptop for 2 weeks, so I dug out the iBook G4 that had been gathering dust for a few years. I bought the iBook in 2005, but never took the time to learn the power of Mac's OS, so I gave up and went back to a Windows laptop. For whatever reason, I found my way around the Mac much better this time around. In fact, I've been using the iBook instead of the (finally) repaired Samsung for everything except spreadsheets. I also bought an iMac in January. I've spent a lot of time on the iMac and I'm now totally sold on Mac. I think I could simplify my computing life if I went to one OS for all my personal computing, but I've already replaced or added to all my tech gadgets in the last year (except for my camera & 3rd gen iPod Nano). My husband is about out of patience for my tech purchases. I could probably get by with selling the Samsung and just using the iBook, but I am a heavy Office user and I would prefer to stick with Office 11. And I keep thinking a 6 year old laptop isn't going to last much longer. After all that rambling, I guess my questions are: 1. Are Core 2 Duo Macbook users generally happy with their laptops, or do a lot of you wish you had spent the extra for a MBP? 2. What are the two biggest advantages to sticking with only one OS? 3. Do those of you who use both Windows and Mac feel using both platforms creates extra work to keep files in sync and backed up, etc? Thanks for any input that will help me decide to stick with my current setup, go for the Macbook, or wait for new MBP models!
