I've been using the iPT5G since it came out, and there are some things that irritate me no end. So I'm thinking about getting an iPT6G, but I'd like to make sure the issues are resolved. 1) Cache-less reloads. My #1 beef. I think this is due to the low RAM the iPT5G has, but the behavior is as follows. Say I'm browsing a news-aggregate page, such as google news. I click on a link that takes me to a new page; when I click back to go back the first news-aggregate page, it doesn't come up in its original form, but instead when I click to go back to it, it re-loads that news-aggregate page anew from the server (instead of bringing it back from memory, as there is not enough RAM to keep it) - and when it reloads, the content is often changed, because the original page has changed in the meanwhile... but I want the original page, since there was content that I was interested in - only now, with the re-load, it is lost. HATE THAT. Q: Does the iPT6G still engage in cache-less reloads? 2) Automatic Ambient Light Adjustment - it existed in iPT4G (which I also owned), and then, in a huge step back, the iPT5G lost it! Incredible, and highly irritating - I'm sick and tired of constantly adjusting the brightness, several times a day. Q: Does the iPT6G have and Ambient Light Sensor that automatically adjusts the light level, like it did on iPT4G? TIA!
