I posted here before and most questions were answered, but I have a few questions that I would like specific answers to. I am and have been a PC user for more years than I can count. So making a move to Mac is quite scary. Presently we have ATT U-Verse for internet. I use the provided modem/router that ATT installed. First Question: Will I need to replace this modem/router or will Mac operate on it? Presently I am wired to the modem via ethernet, so I am a bit lost on the "wireless" setup. Will I need a wireless router? If so, which is reccommended? Second Question: My wife has a Dell laptop that connects to the wireless network I have installed. Will this affetc her ability to connect? Third Question: Will I need a new printer and scanner? Both are HP and both for use with Windows. Will this affect my wife's laptop printing? I apologize for the probably mundane silly questions. I can hook PC's up in my sleep, but switching to Mac scares the heck outta me!!!! Thanks so much. Oh, I am considering purchasing the new iMac i5 with 4gb memory and a 500gb hard-drive.
