I'm not sure what the point is comparing the KA1 with the oasis. For better or for worse, there's a big size differential, like an iPad mini vs a regular iPad. Also, if someone (like me, for example) doesn't use a cover, then having to pay for an included cover is a big minus.
I didn't buy the KA1 after reading the reviews here and deciding on the whole against it. Went with a refurbed voyage for $120 instead.
But I would've liked a larger screen. I notice I use a bigger font when reading on my 10.5" tablet just because there's more room. On the 6" kindle, I'm using a slightly smaller font than strictly comfortable just so I can have a decent amount of text on screen. As for the size, it seems to me the bigger size is better for reading in bed because it's actually easier to prop a larger device up on my chest when lying on my back or against the pillow when lying on my side. It's only when I'm out and about that the larger size may be a problem. I probably shouldn't be reading while walking anyway
