Hi Steve
Glad that you sorted out your challenges, you sounded really stressed on Sunday evening when it all went fubar!
The combo you now own seems to be a good optimum. I use a similar concept, but older, combination. I'm now finding my 3 yr old Acer laptop is becoming flakey, so I'm thinking it's time to do something about it!
My 3.5 yr old Sony P4 desktop has been upgraded so many times now, with 2GB RAM, 2 x 200GB SATA drives, 500GB of external drives, new KB/mouse/tablet, new monitor, etc., it only has the original case and motherboard left! Hopefully it will last another year or so.
Regarding camera bodies, I guess you're right, but I haven't developed my own techniques sufficiently to utilise more than about 25% of what the K10D is capable of, let alone run into VPN, BF, FF, etc., etc., in normal use!...
The main reason I bought it was for faster operation and a bigger buffer, the other stuff came as extras.
I guess you could call me a natural "late adopter"
It was very unusual for me to rush in and buy the K10D when it first appeared, I was actually a bit nervous doing so, it actually took me all of 5 minutes to decide (a nanosecond for me!) but you know the reason why!
As far as buying a second body, that's not for me, I'll do lenses long before that, I'm hoping I can reduce the number of lenses I have and replace them with the new DA* zooms, if they live up to expectation!
Currently I'm agonising whether or not to spend a whopping £25 on a new small bag for casual use! My frugality is impresssive, don't you think?
