Me too! I only picked up a DS Lite two years after launch (on the day the Lime Green model was released, which is what I own), it really was leaps and bounds ahead of the DS Phat.
Though I think my model was one of the ones with the inferior screens (earlier DS Lites had higher quality ones if I recall correctly), but it was such a step up from the DS (Game Boy Micro quality screens and backlighting!) that I didn't care.
Which reminds me: a friend of mine from outside the forum owns a GBA SP backlight edition. I am jealous. That bought those kind of improved screens to GBA SP form factor, and it's really nice.
