I've been reading e-books for something like 25 years, and my book collection won't fit on ANY portable device.
Once you acknowledge that you need to be selective about what you have with you, it doesn't really matter very much whether you can "only" carry around 100 books or 10,000. Both are "large numbers" in terms of reading material (100 books is probably a year's reading for me).
So, personally I'm not particularly bothered. I have devices with a memory card slot, but I don't use it (other than, for obvious reasons, on the iRex DR1000!).
