Mostly what I do on the computer is edit travel photos with Picasa, and put into photo books like Shutterfly, I want to get deeper into editing including learning how to put together video highlight shows of trips. I'm been a pc person for 20 years and am confused when other show me Mac, and all my saved files have been put together using PCs rather than Mac, so I would be worried about moving into the Mac world and leaving my old files and programs behind while learning how to use Mac OS, so I'm leaning towards staying with PCs. Also, it doesn't need to be a laptop -- a desktop tower would be fine.
Are there any recommendations regarding products, processors, storage space that you may be very happy with for similar use? Also, I bought a monitor with Groupon last year that's still in a box (doesn't work with my current pc), so I already have a monitor ready to go.
Thanks for any suggestions!
