I discovered that while the Apple OSX upgrade was much cheaper that what Microsoft does, the gotcha was in the software that nolonger worked. My upgrade from Leopard to Snow went with a cheap $29.95 however nearly all my software became unusable. The upgrades for all the software was over $600! Most of that was in Final Cut Pro but other apps also needed upgrade.
So, I have decided to convert my Macbook pro to a handmedown. I was looking into the future of it for my son-in-law who said he would love to have it. But I question is this Mac has now reached a dead end with Leopard Snow ??? I'm not sure since it is a MacBook Pro 15" 2,2 version. It's the same one that Scott bought as we got ours the same month he got his that year and I don't recall when that was without digging through my records. It has hardly any use on it but it seems the battery won't charge. I haven't turned it on on well over a year, maybe 2.
