I saw your post on that other thread. It's one of the main reasons why I considered this watch. I don't think the keyboard would be an issue if I can get logged in as I usually stick to my saved stations. Would you let me know if you decide to install Pandora and how it goes of you do?
sorry for the late response, been busy at work. confirmed that pandora works with the watch though the interface might be a tad bit small given the screen size. however, if you've saved stations then you should be just fine. as mentioned previously, once you start using the keyboard, you have to be patient with it. i still make the occassional mistake but i rarely use the keyboard as i'm happy with the setup. in the other ik8 thread, drlex recommended using slide pass as an alternative to the built in keyboard. haven't tried it out yet but it seems to work well.
you'll definitely need to use bluetooth to pair a good set of earphones. the watch doesn't have a 3.5 jack and the earphones which come with it aren't really tops. i've already paired the watch with an old itech unit, coupled with my senheiser buds. works well. battery should be enough for you if you're out for a run...though i'm not sure if it'll last if say you're doing a 5-hour marathon. i've used gps on it for like 3 hours riding on my bike and it went down 50%.
one thing to be careful though is using the watch in the gym. the specs do not mention "water resistant" unlike other watches which claim to be (which i don't really believe). you might need to wear something like a wrist band undernearth to protech the watch from sweat. same goes for running outside.
cheers
