I've reached the point where I need to buy an ebook reader. I find myself spending more time with the internet/computer and less time going to the library

(Though I still buy lots of used paperbacks).
Based on price and features (after reading this forum and others), my choices seem to be the Ebookwise 1150 or the Nokia 800 internet tablet. I'm in Canada, and the prices of these two, after shipping charges to get the Ebookwise from the US here, are almost the same.
On the one hand, Ebookwise seems to be the clear winner of these two in terms of format and displaying a book, as well as sturdiness.
The Nokia on the other hand has tons of extra features (internet, audio, video and a Linux OS to tinker with), and is also newer technology. From what I've read, however, the Nokia's smaller screen makes reading novels much less pleasurable than on the Ebookwise.
In your opinion, what is the deal breaker? Should I go with Ebookwise's "reader's screen", despite the device's limitations, or is the Nokia's screen adequate, especially when combined with extra features?
