A Refurbished iMac is a very good deal. Get it from Apple, not eBay.
There is very little software does not work with 10.6, you just need to figure out what it is that you have extra and check on their website.
Most of the utilities have now been updated and, if you are the purchasing of an older version, the upgrade is usually free.
Office 2004 does not work too well under SL, but it is usable. There are alternatives.
Got the bug to upgrade my iMac G5, 10.4.11. Question: jump to 10.5 or big jump to 10.6? Is there a big difference between 10.5 and 10.6? I'm on a budget and looking for the best deal around--don't want to get ripped off. Refurbished iMac a good deal? Ebay? Apple store? Other? I do a lot with pics, writing, some graphics and I like speed and storage. There is a cost in replacing some software I already have (Disk Warrior 39) that I understand 10.6 doesn't accept. I think there's a place to verify what softwares are compatible. Right? What is it called?
Any suggestions would be very appreciated. Thanks.
