I bought this one a few months back for $250 in immaculate condition with 2.5GHz C2D, 4GB DDR2, glossy display and 8600M GT. I ran the dosdude patch on it so that it can run Mojave, and have pretty much used it just about every day since for web browsing, coding, photo editing and such. The battery holds a couple hours of charge, and it just runs really well. Sure sometimes it bogs down when trying to run multiple apps, but I put an SSD in it so its quick enough. I think the worst part is the 4GB RAM. I read these can take 6GB but have not upgraded it yet. For under $300, I feel that these are still a great portable machine with nice keyboard, nice size display, and the ability to run up to Catalina thanks to dosdude, and maybe big sur? Have not tried it yet. Anyone else still use one of these all the time?
