I've been wanting a DSLR for a few years, but held back from the high
prices, confusing specs and profusion of models, and the rapid
technological improvements that kept coming through.  I had "decision
paralysis" for a long time.  Now I'm past that, and for me the time has
finally come.  Today I placed my order for a new Pentax K100D.

Yeah, it's only 6.1 MP.  I know from experience that 3008x2008 pixel
images will be plenty good for the vast majority of my uses.  The new
Pentax K10D will attain 10.0 MP.   That translates to about 64% more
data produced that I have to store and process, while the increased
definition would rarely (if ever) be useful to me.  So. . .  In my case
I actually preferred the lower MP count.

It has anti-shake technology that works with almost any Pentax lens?  
Count me in!

It uses ordinary SD cards for storage and, more importantly, it uses
four AA batteries.  There's not many DSLRs out there using standard AA
batteries; it can take NiMH, Li-ion, or even alkaline batteries in an
emergency.  This gives me a sense of comfort because I might possibly
be using this camera for a very long time.  I used the same 35mm SLR
for more than 15 years and would have kept using it indefinitely if I
hadn't felt the need to get away from film.  Ten years from now I might
not be able to find an oddball Pentax SL7-9938-A2 Li-ion battery pack,
but I'm pretty sure I'll be able to get AAs in some form.
