Here and now works flawlessly on my N82. Also, the app looks very nice. It's great to see S60 apps really picking up speed in this area.
At the same time, Here and now could have been better. First, it could have utilised more of the screen area. I hope they'll implement a 'full screen' option in the future. Second, why focus so much on telling me what the weather is like right here and now? I am here right now, aren't I? I can see for myself what the weather is like. I would much rather see what the weather is going to be like for the rest of the day, and tomorrow. Especially if you click to see more on the weather screen, you see a web page where the whole screen tells you what you already know. You have to scroll to see the forecast for coming days.
The events section seems useful, though, even if I can't tell how complete it is.
All in all, a nice and useful app that I would definitely recommend, but it needs some rethinking.
