Thanks to my director, Andrea Kim, I've been able to upgrade from my old rickety Dell Latitude D800 to flashy mobile Latitude D610. With a 2Ghz/1.32 Bus, 2G Ram/80G HDD, it's a decent developer machine. The only down side was abandoning the wide screen so I made up by putting a 17 inch LCD next to it. With Intel Centrino processor, an approx 4 hour battery life was a big plus. One of the possible choices was D810 but its much more heavier and thicker in size than even D800, and hence disregarded.
So far, I'm loving it!
