EARLIER TODAY I MENTIONED Netflix streaming via the Roku device, but now reader Denise Stevenson emails: “Amazon just released a beta version of their streaming service on the Roku on Tuesday. Works great, with better selection and quality than the Netflix stuff.” That’s cool. Maybe they can put PJTV on the Roku, too . . . .

UPDATE: Jim Treacher emails: “I got a Roku for Christmas and it’s fantastic. You don’t get the full selection of movies they’ve got on DVD, but there’s a hell of a lot. Waiting for discs to go back and forth in the mail seems silly now. I say go ahead and let the Postal Service go to 5 days a week.”
