I just picked up a new laptop (Acer 5780-5740) which includes 802.11n (draft). I'm thinking of upgrading my router to support the wireless-n. However, in a brief look at new routers, I *thought* I saw a couple of different standards for 802.11n - some that just say draft, some that say draft 2.0, some that don't say anything other than 802.11n.

Are these all the same? i.e., will pretty much any router that includes 802.11n work the same as the others?

Has anyone noticed an improved signal with 802.11n? Speed increase is great, but I wasn't planning on doing much file transfers - just internet. I've heard the signal has better range and robustness but was just curious whether anyone has actually experienced this.
