what is diff between prs-500 and 505?

From https://wiki.mobileread.com/wiki/PRS505:

As compared to the PRS-500 the following improvements are noted. The PRS-505 has the ability to categorize books, the ability to connect to any USB port and look like a memory device / card reader, and the ability to fully charge from any USB port. The 505 has more color choices for the case, a whiter screen with more contrast, faster page turns, more gray scales (8 vs. 4) for better images, a better connect interface to the Sony store.
