If you sign up for the MR e-mail list, you'll get a few special discount offers per year on some of their products, including MR subscriptions. Most of the things in the e-mail newsletter are fluff but there is an occasional nugget of information that's worth having.
As for paper vs digital, I'm in both camps. I have the last couple of issues of MRH on my Palm so I can read it when I have the odd moment, something you can't do with a paper magazine. OTOH, there's something about really good photographs on glossy paper that's hard to beat. I think both mediums will exist side-by-side for a long time.
Remind when palm whas the wonderfull new gagdet ! i had a palm M125.
what would be really nice is if they would give you free access to the pdf version if you are a montly suscribers. in fact the governent archive/library do it, they now pdf-ize all the stuff they have so we can acces it online
