I got a Samsung monitor for Christmas to go along with my MacBook. The only problem is that I don't have a keyboard or a mini DVI converter cable. The monitor came with a VGA extender; however, I'm not sure if I should use a VGA or DVI cable to connect it to the MacBook. How much better is DVI than VGA? I need to decide now since I'm going to the Apple store to either get a mini DVI to VGA or mini DVI to DVI cable tomorrow. If I do use DVI I'll need to get a DVI extender. Also, I'm not sure if I should get a wired or wireless Apple keyboard. Is the wireless worth the extra $20? Thanks, and Merry Christmas.
