well if you just scroll down a bit, you'll find a "minimum circuit" that don't even have a xtal and capacitors.
in my minimum mega8 ardiunoisp design, except for pwr bypass, there are no external components at all. so far ive built several dozen of these for others with no problem. also with modern crystals and proper fuse settings theres less reason for those two caps there.
but if you want to run the target avr after you unplug all the wires to your arduino, you'll want that 10k res (instead of connecting RESET directly to VCC) anyway.
i disagree. for some reason builders, specially hobbyists, like to attach as many unnecessary components as possible. in the case of reset circuit it often creates far more problems than it solves. in particular throwing in caps which turns out to be a major reason nooby circuits wont program.
imo NOTHING is the best thing to hook up to that pin. as long as you dont go around poking it with metal tools or place megawatt welder 1" away problems are rare. of course, as always, for mission critical applications its best to adhere to atmel specs to the letter. not so much for technical but rather liability reasons.
