Hey all, I have been considering giving Lion server a try now it's nice and cheap, but I'm a bit unsure exactly how much I can get out of it and basically whether it's worth a go or not? I apologise if my questions are a wee bit noobish, but if anyone could clear them up for me that'd be great! I've got an early 2008 24" iMac 3.06GHz Core 2 Duo 4GB RAM, late 2009 MacBook Pro 2.26GHz Core 2 Duo 8GB RAM, iPhone 4 & iPad 2, if that helps! Firstly (a very daft question I'm sure but I just want to check), do you only need to install the Lion server on one computer, and then as many others as you want can access it? I'll be going back to uni in September and a couple of others in my house have slightly older MacBooks, would they just be able to connect to my server (say for arguments sake I install it on the iMac) and access and stream any files I have on it, music or movies etc (assuming they have Lion installed)? Just to make sure I understand, will it also keep everything in sync between all my devices, mail, contacts, calendar etc? One of the more frustrating things I've found with having two computers on the go, is the fact that I might file some emails away in a certain folder/mailbox on my MBP, then they're nowhere to be found on my iMac? I've got a 1.5 TB external HD that i've been using for backups, would I be able to just leave this connected to my iMac and have my MBP backup onto that HD over the network, as well as having my iMac back up to it also? Lastly, will there be any noticeable performance hit on my iMac if i have this running? Apologies if anythings not very clear, any answers would be greatly appreciated Cheers all!
