Just wanted to give a quick update. I got my refurbished MacBook Pro on Friday. It was in perfect condition; no problems there. So far I love it, although I am still getting used to it. For any others who were wondering about some of the same I questions as I was, here are my updates:
Hotmail works great with Entourage, although one of my accounts is a premium one and the other is a very old one, so I don't know if it would be different with newer Hotmail accounts. Httpmail wasn't that great for me, because it basically just allows Mail to download the Inbox, but you can't use all the folders. Having synchronized folders is what I like about Hotmail. I am not a fan of pop mail accounts.
I decided to just sync Windows Mobile with the XP side, so I haven't bothered with Missing Sync or anything like that. As far as tethering goes, it was a little weird. USB tethering works with the XP side, but I can't get Bluetooth tethering to work. On the Mac side, Bluetooth tethering works fine, but not USB. Using XP in a virtual machine does not allow USB tethering - it has to be booted separately. At any rate, I have a tethering solution with each platform, so that's good enough for me, since it's something I really only use as a backup if I'm somewhere I can't get WiFi.
Synchronizing my iPhone was no issue, not that I expected it to be. I was pleasantly surprised that it imported all of my contact and calendar entries to iCal and Address Book without my having to export them from Outlook.
My VPN for work works, but only through Firefox. I couldn't get the Citrix web and Safari to play nicely together.
Getting Windows loaded was the only tricky part, although I can't really blame it on Apple or Microsoft, really. I know it said you have to have a full, non-OEM, non upgrade version of Windows. I have a non-OEM copy of XP, but it is an upgrade version. I thought it might still be okay since I had an old Windows 98 disk to put in during the install to prove I had Windows, but I wasn't thinking it through clearly, because during the reboot, there was no way to switch out the CDs! Very annoying, since all of these copies of Windows are legal, legitimate copies. It's just a glitch of the optical drive not being able to eject the CD during the install process. Anyway, a friend fixed up a CD for me that made Windows happy, I used my legal installation key, and all is well. I guess it shouldn't be too surprising that Windows was the only hiccup! But Windows itself works fine, in fact better than on my old Dell, since it was a clean install without all the crapware they put on there.
Anyway, so far I am happy, though still trying to get the hang of the different keyboard and some things about how the files are set up. I am also struggling to get videos off my TiVo. Other than that, though, I think I'm a convert, and glad I made the switch!
