he he, I knew this would turn into a looong thread :)
Couple of points and my personal observations FWIW, obviously:
- you do not need DSLR to take great pictures or learn the craft.
- DSLR gives you flexibility of the whole system ie lenses, accessories etc, and opportunity to take pictures in a challenging conditions ie low light and/or fast moving subjects.
- not all DSLRs are equal - try before you buy, or at least just look through the 'peep hole' of a couple on your shortlist (with the same lens attached) before you commit your money.
- lenses are forever and your best friends. (c) VDG ;)
- old bodies do not stop taking photos just because MKII/s/x/f is released.
- as with any hobby, there is no limit to how crazy far you can take it. Buy what you need, not what you may need.
- I recently realised that 90% of my (crappy) photos, including holiday/travel snaps nowadays are taken with iPhone
