Honestly...why would you drive a sports car on an open highway at 45 when there are lanes open and you can get it to go full throttle??
You device is capable of so much more!!

Flash...definitely
devote a Saturday for your first time...absolutely
start with a LOT of reading...esp the stickied threads in the upgrade forum
have a couple of ROMs already in mind before you begin (the "popular" ones are always a good place to start)
LEARN AND KNOW HOW TO PUT YOUR PHONE INTO BOOTLOADER MODE before you start flashing so that way if you "mess it up" you can still flash a ROM (stock) to start over
Always have the stock ROM handy...for those unfortunate incidents that you have to go back to stock
Expect bugs...they happen...its software...can't really get away from that
AND...it is addicting...and before you know it, you'll be asking to be convinced to cook YOUR own ROM...and ask for advice on which kitchen to use!! (Calkulin's is my personal favorite.)
