There is hope at docking stations in general (HTC LEGEND SYNC AND CHARGER DOCKING STATION - HTC Legend
), however to be honest, HTC popularity is pretty new and largely linked to Android. Therefore, if there was such a station (alarm etc. as you want), it probably would be a little while before it came out. It's like, I had to wait a few weeks, a month even, before I could find silicon cases for my Legend available in UK.
Additionally, if you're matching up Legend vs iPhone, well iPhone WILL win in terms of the accessories. Accessories and generally addons are one of the key focuses of Apple's business model. For a while now they've pumped money into developing things to add on to their devices - earphones, docking stations, radios, speakers, heck, even my TV has a dock!. Apple is after all a .. 'clique' of sorts, so they know that once someone gets an Apple device, they probably will follow suit with all the accessories. HTC does not put nearly as much effort into these accessories, hence a longer wait (if at all) for them.
All-in-all I luv my Legend, and as compared to iPhone, I luv the flexibility and ABSENCE of 'vendor lock in'.
