Interesting device. Not exactly priced as cheaply as other eBook readers but of course it is much more capable than that. Just annoyed that the 3G capability costs an extra $130. Though like the iPod Touch, many will fine WIFI only capability enough.
I think if it imported and handled camera RAW files and had a regular USB port instead of needing that camera photo adapter, it would be a great travel companion for photographers.
I am really interested in the initial comments about the speed of the device from Daring Fireball.
