My psychology professor in college (many years ago) said, "You want to live long? Have a hobby when you retire." So here I am with retirement a few years away, looking to develop a photography hobby. But I'm also a gadget guy and love small electronics. The idea of lugging around a bag with a DSLR and lenses, filters, flash etc., doesn't excite me. I have read articles about a few isolated photographers who are the exception and exclusively use point and shoots. So here's the question. I own an advanced Lumix point and shoot. Is it possible to develop an amateur-level, but serious photo hobby, and remain an "undergrad", never going to the SLR world? I am enticed by several other advanced point and shoots, like the Canon G10, and will probably end up owning a few. I would like to hear from people who are committed to being "undergrads" (anyone?), their successes and failures, satisfaction and frustration, hints and suggestions. Thanks in advance.
