I have had my sidekickII for over 7 months now and have used it on a daily basis. Just yesterday, however, it downloaded the 'upgrades' which include JavaScript and now it is slower than ever. If you get the upgrade notice, DO NOT upgrade unless you want your pages to load even slower than they do now. The icon for the phone on the main screen was also changed on the upgrade. It doesn't show the 'open, close' screen anymore. I mainly use my sidekick for chatting with relatives on AIM on the east coast and it is awesome for that. I would highly recommend it for touring bikers (like myself) and others who want to keep up with local road and weather conditions. I have several weather sites on my bookmarks which are awesome for traveling. It also helps you keep in touch while you are on the road. I do wish it could send pics in the AIM or Yahoo chat sessions, but I doubt they will ever add that feature. The quality of the camera photos is not as good as other mobile phone models, but when you email them, the quality is better than the screen quality you see on the Sidekick. I highly recommend you buy a car charger because the battery only lasts a few days and if you get below three bars, the web browser doesn't work at all. I love the qwerty keypad, although after chatting for awhile my thumbs get sore. The on/off, volume and picture 'keys' on the corners of the unit are not user friendly at all and are hard to push in. I use the scroll feature for these functions instead. I rarely use it for calls (I have another cell phone that is a cheaper deal for that) because they are more expensive than other plans (especially if you get the pay as you go model because you have to pay for incoming voice mail and txt msg's too). I do love it for checking my home email when I am away. It will hold up to three external email addresses and has a great address book and note feature. Again, it is GREAT for AIM and Yahoo msg chats and for wireless web browsing, but the new javascript upgrade slows it down tremendously. It made my yahoo web mail almost too much trouble to access. It's great for teenagers who love to chat with friends, but I am pushing 50 and don't find it ergonomically correct if you have any arthritis. I am waiting for a Bluetooth (high speed) model to come on the market that also has AIM and Yahoo MSG and I will likely replace my sidekick...or give it to a well deserving teenager.
