Good things so far: getting online through wifi has to be the biggest thing. It's a big reason why I got it. Browser, mail client, maps, AIM, anything I need fits in my pocket. Plus, I can download the same apps and games as the iPhone, so even more shot fits in my pocket. And most wifi is free. As a pure iPod, it's 4 times the capacity of my Nano, plus plays vids and stores pics. I can even type in 日本語. And on top of all that, it was only $225 used!
Not good so far: It seems that there are lots of open wifi networks, but few of them seem to actually be able to get me online. Typically, i join a network, but still nothing connects. So i have to take advantage of the ones that do work, like the one on this bus. watching videos is a huge drain on battery life, and even using the web plus music, I'd say it only lasts a few hours. It was used, so the battery probably isn't what it used to be. The keyboard takes getting used to, since it is screen based and has no physical buttons, and the buttons are quite small.. It's a lot easier to use when the keyboard is sideways and the buttons are larger, but only a few apps support landscape orientation (the browser is one of them). I haven't figured out how to select or cut and paste text. Also, for some reason, my headphones work super quietly on here, so I have to either use shitty earbuds or get new ones.
Overall, I'm really happy that I have it, and can do much more on the road now (like check LJ). Hopefully thisll help a lot my ability to keep up and keep in touch.
