Hello all, I am finally taking the plunge into the Mac world, and have a few questions before I order a new MacBook. A good friend of mine bought a Mac about a year ago, and has convinced me that a Mac is the way to go. I am somewhat nervous, though, because I know nothing about the Mac OS (of course). Also, I am unsure about any of the possible software and hardware constraints that may come with using a Mac, as far as my uses are concerned. 1. Will my USB external hard drive (Western Digital 250 gb) work seemlessly with a MacBook? The plug-n-play (so to speak) ability with my Dell laptop is very nice. Will a MacBook accept and recognize the hard drive, too? 2. Could I use an external USB DVD burner with a MacBook? Are there only certain "Mac compatible" DVD burners, or would any of them work? I am thinking about getting a MacBook with a Combo, and hooking up an external burner for the few time I actually need one. I can get one on newegg.com for the $60-$70 range. 3. I use my Microsoft Streets and Trips mapping program A LOT. I have read about using Microsoft software on Macs, but wonder if Mac has map software of their own. I haven't been able to find very many (1, actually---Delorme Street Atlas, I think). The GPS antennae that came with my Microsoft Street and Trips 2006 turns my Dell into a great navigation tool on long trips. I hope I can find the same type of software for a MacBook. Any thoughts? 4. Will there be any issues with connecting my Nikon D50 digital SLR camera to a MacBook? My Dell recognizes it and asigns it a drive letter. I can pull pictures off it very easily. Any issues with a MacBook? (sorry if these questions seem ridiculous) 5. If I order a MacBook and it doesnt come with the absolute latest version of Tiger (10.4.9 I think???), is there any easy way to download the update? Does it cost anything to update to the latest Tiger version? I understand the cost associated with an entirely new OS (Leopard, when it comes out), but just wonder about the latest version of the Tiger OS. 6. I have a Linksys wireless internet router. Obviosuly, my Dell is configured to pick up the signal as soon as it is powered up, and I am cruising the net very quickly. Will a MacBook pick up the router's sigal as well, or do I need to get an Apple router? My Linksys router isnt currently encrypted (not an issue where I live), so does that help my situation? Hey, I have a lot more thoughts and questions, but I will end it here. If anyone could help, I would truly appreciate it. Thanks again!!!
