I'm still using my powerbook G4, 1.5GHz, 1.25GB ram, 10.4.9 tiger bought it new in February 2006. the harddrive is making more and more noise these days still running the original TOSHIBA MK8026GAX 80GB, ide ata-100, 5400rpm, buffer 16mb. seems there aren't many options for upgrading this thing without going down to 8mb buffering, or moving to 7200rpm. Or putting in a SATA converter, and with the 12" powerbook there isn't much room for that without going down to a 1.8" size drive... what about a solid state Transcend 2.5" TS128GSSD25-M 128GB SSD? and if that works, is there any great performance advantage to upgrade the OS X to 10.5 leopard? thanks for any input/options to help me keep my powerbook on the road!
