So what's actually new here? The real difference is in the amount of storage and the total cost. The original Kindle Colorsoft is $280 with 32GB of storage. So the newer version has half the storage for only $30 less. For those who don't want to pay more for storage they won't use, this is now the Colorsoft to buy. Though at $250, it's worth considering alternative reading tablets that are capable of doing more. Especially if you plan on reading a lot of comics digitally and need that extra storage space.
The other new item here is the first-ever Kindle Colorsoft for kids. The kids editions of any of the Kindle models are essentially the exact same device, but with a fun cover included and a 12-month subscription to Kids+ rather than Kindle Unlimited.
