I've been wanting to get a new computer and was considering the 305 since I read how much you loved yours. When I spoke with the Garmin folks about the Sea Otter about the calorie count issues, one thing really struck me: they really don't see what the big deal is. These folks are GPS folks through and through. I've used their products for years on my sail boat and have been happy, but really, that's just mapping functionality. They really have no idea about the needs of atheletes, nor do they care. They couldn't even give me a rough estimate about when they'd fix the calorie bug because they had so many "more important" bugs that they were going to address first. When I asked about the "more important" bugs, they spoke all about was mapping issues -- nothing else mattered. I'm holding off until they get your issues fixed.
