The pricing was announced today for Wizards Dungeons and Dragons Insider at Welcome to Digital Insider!. So the real question for me is whether the parts of D&DI that won't suck (like the Dragon and Dungeon content) are worth $5 per month. By the way that price is for a 12 month subscription.
Here is the price breakdown.
Web-Content Only Subscription Package:
12 Months = $59.40 ($4.95 per month)
3 Months = $19.95 ($6.65 per month)
1 Month = $7.95 ($7.95 per month)
If by some miracle the other computer tools don't suck (and actually work on Linux) those would be like icing on the cake really. I think their current pricing reflects the fact that their tools will suck (and they know it) and that people won't pay for them, but that people will pay for the magazine content. I would pay $5 per month for the magazine content so they will probably have me for a subscriber.
