As a book reader, I often find myself using the N900 in preference to the Kindle, which is equally in reach here. The N810 is even better as a book reader, but the N900 can do so much more so much faster. The browser alone is incredible on the N900. Witter is a great Twitter client for the N900. And lots of the programs that were so good on the N810 are faster and nicer on the N900.
