Alright, sell me on why I should get a Forerunner 405 ....

Sorry, I don't have an answer for you, just a question...

How on earth does one get their wife to want them to have ultra-equipped gadgets?  How many anniversaries does that take, because I just had my first one a couple of days ago and I'm pretty sure that not even the most under-equipped gadgets made my wife's list of potential presents.

Are you the luckiest man alive?

The only advantage to the 405 (other than it makes the other version cheaper) is it can be used as a regular watch.  Personally I don't care that my 305 is slightly bigger than my IM watch.  I only wear it to train. 

In the future (if anyone at garmin is watching) I would like to see a truely waterproof version along with a battery to last at least 24 hrs.  Until that happens I will keep my 305.

Pretty much the same for me. A couple of weeks ago I thought I'd lost my 305 and was trying to decide between the 405 and 305 for a replacement. While I liked the size of the 405 for being able to use it as a watch, I wasn't sure how well it work as a bike computer due to the size of the characters and only being able to have 3 data fields displayed at a time.

Fortunately, my 305 got returned to me so I didn't have to make the decision, but I was leaning towards getting another 305.  

Well, she did say yes when I asked her to marry me, so I must be!!

Okay, thanks all, that's kind of what I wanted to hear.  My old boss from the bike shop actually was trying to sell me on the 705 for cycling also.

I'll read up more on the 305 and see whether I like it or not.  It would pretty much only get used for training, but we'll see if we even go that route to begin with.

Yep, that would be the thing to get me to upgrade my 305 also.

I got a 305 for Christmas last year.  Didn't ask for it and probably wouldn't have gotten it for myself, but I have to admit that I like being able to check my pace/distance during a run no matter where I am (don't need it so much for routes I do frequently and already have a good idea of pace/distance). 

For the bike, I wear it on my wrist and just use it to map my ride out later (get climbing data, etc.).  If you don't need/care about the HR, you could just get a 205.  I've used it for a duathlon, but not for a tri since you can't swim with it--can't see the reason to bother putting it on my wrist in the middle of a race.

It's a nice toy.

Yeah, I know it can be done.  But I don't need the data that bad.  They'll tell me my time after the race. 

Or...you could get a Polar S625X that you can actually use as a watch, don't have to charge and swim with.

Just saying.  Plus there is no losing or waiting for satellites.

BUT, the downloading graphs and routes is kinda cool.
