With so many amazing accessories for the iPad it's getting pretty pricey but well worth it!! I guess that's another reason why the Xoom isn't doing so good....
So Far:
$40 - Griffin case on launch day
$39 - HDMI adapter on launch day
$15 - Targus Stylus
$9 - Nataal Stylus
Future:
$40-$80 - New Case
$10-$30 - Screen Protector
=\
$20 iLuv case
$50 incase magazine case
$40 HDMI Adapter
$20 Stand
and im thinking of getting the usb camera and SD card reader?
Your total cost will equal the price of replacing any possible damage that may occur to your device. Waste of money if you ask me.
