Why is nothing less than 64gB going to be adequate - your statement and following assumption begins with a nonsensical conclusion. Why do you need the SD adapter and the USB one? If you already have a bluetooth keyboard why do you need to buy another one. $499 will do just what I need this device to do. I'm not replacing a laptop, I'm seeing this device for what it is and browsing the web (no need for storage) reading a book (can't be that big a file) or listening to some music (again, 64gig covers most peoples audio listening for a few days.) All at home on my wireless N network. Easy. $499. No more.
"Since this device is intended principally for the consumption of visual media" Is it? I thought it was principally for reading books, browsing the web and checking yr email?
