I have a 15" Powerbook G4 DLSD/HR 100G 7200 RPM 2G DDR2 and it is completely stock. I still use it daily, but it just seem so slow and won't play flash. It's too good of a machine to stop using so I am considering if it would be best to get Leopard so that I can update my iTunes, Flash, etc or can I tweak it on Tiger enough to feel updated.. Is it worth it? I've read a lot of the forums on Flash and tried the download that makes my flash read as 11.5, but it doesn't seem to help my YouTube and it still won't play flash on Facebook. I also looked at the Webkit, but that seems to be only for Leopard? Which again begs should I try that? Further on that point, can I install Leopard from an old MB setup disk? Sorry, I'm sure these topics have been covered somewhere and I have read a lot that seem to be close to what I'm asking, but nothing that is specific to my hardware.
