The ones that keep offering Time Capsule and Airdisk as an alternative may not.
Seriously speaking.
That's a pretty obnoxious and even insulting statement.
The vast majority of features touted by the HP server can be had using a Time Capsule. Might the HP do a better job of delivering some of those features? Sure. But the cost of a Time Capsule is hundreds less than the HP server and some people here may already own a Time Capsule and just not be aware that they can use it for many of the same functions as the HP server. I know at least one guy responded to my post sounding awfully surprised that he could do what I mentioned. I also chatted with tech reviewer from a respected news source who was unaware of this and they DID a review of the Time Capsule. So clearly no everyone is aware of this.
If you have the hots for this HP server, you should go buy one. Its probably a fine device. I don't have anything in particular against it except that it does not fit my personal needs at the cost.
