I have a Touch, a Glo and an Arc. I tend to hold my book/reader at eye-level and the Arc is a little too heavy for this style of use. If you read with the reader flat on a desk or table, this may not be an issue.
That said however, I think the Arc is an excellent bare-bones 7in Android tablet. The screen is quite pretty and the colours are quite contrasty. Arc's touch response is undoubtedly the best out of all three Kobo devices I have but for reading books, I prefer my Glo. Lighter and less strain on the eyes.
I'm not sure why there's such a fuss over the pesky "Tapestry" and "Discovery" apps. Any one of the alternative launchers available through Google Play will hide them from view and replace it with an arguably cleaner and more functional interface.
Here's a good intro to alternative launchers:

For a good measure, all Kobo apps can be disabled from Settings>Apps>ALL> But this will essentially turn Arc into a plain vanilla Android tablet. And as such, its really not bad at all!
