Hello All,I'm currently looking into purchasing a laptop for my photo needs out in the field. I'm a PC user at home with a desktop that has only 2mb of RAM and an i3 processor, needless to say it's VERY slow. While I'm out in the field (Race tracks, etc.) I want to be able to transfer image files to "Dropbox" etc. so I need wireless capabilities and plenty of speed for lightroom, etc. I'd prefer a 17" display, but I'm willing to make do with 15" if I need to put the money towards processor speed and more RAM. So does anybody currently have any recommendations out there ??? I don't have a TON of $$$ to spend, but I want to buy something that I won't need to upgrade in a few months. Make/Model & Prices PLEASE and Thank YouPS. I'd like to stay with a PC based laptop vs. Apple/Mac.
