Yeah, I've admired the Panasonic Lumix. IIRC, the lenses are made by Leica, which has an excellent reputation. (Leica's own digital cameras are very pricey.) However, if I upgraded to a higher-end digital camera, I think I'd like an SLR with detachable lenses (e.g., telephoto, wide angle, etc). AFAIK, this isn't an option with the Lumix cameras. So I'd guess that I'd probably end up with a Nikon or Canon if I upgraded.
