Hi guys. I just want to post a quick question before an OS upgrade. I've been searching the web for this and I just found some old info regarding 10.5 and 10.5.1 I have 3 macs and never tried a PPC one with Leopard. So, does anyone here runs a 12" PB 1.5Ghz (or less) with 1.25GB of ram with 10.5.4? How does it run? A lot slower than Tiger? Problems with core image? Is Java slower? Scrolling through pages is a pain in the neck? Will the ram be enough for some PS and LightRoom? Should I expect lags in finder? Again, I did a lot of research but the posts where from 10.5 and 10.5.1 and I'd like to hear recent information. Thanks a lot for any input!
