Ask HN: MacRumors Buyer's Guide for all gadgets?

I bought my dad a Kindle for Father's Day last year. One week later, the Kindle 3 comes out. Needless to say, I'm unhappy about this. But instead of getting mad I decided to get even: my best friend and I have been working nights on a MacRumors Buyer's Guide for ALL gadgets these past couple weeks [1]. (It's almost ready to open up to private-beta http://isitnewyet.com)

The idea is what if you could see into the future and know in advance when gadgets were going to be updated and released?

Would a MacRumors Buyer's Guide for all gadgets be useful to you? We would love all the feedback and insight we can get. Thanks HN!

[1] buyersguide.macrumors.com—The key to the MRBG is their product cycle-based buying recommendation. For example, say you want to buy an iMac. As of today, the iMac has not been updated in 206 days. The iMac's average refresh cycle is 226 days, so MRBG recommends "Buy only if you need it - Approaching the end of a cycle." It's not perfect, but now you've got a more complete picture before you make you make the purchase.
