I purchased my i90c for its impressive feature list, since it matches well with my gadget-crazed personality. It's fairly large and won't be fitting into your front shirt pocket.Belt holster - the phone snaps into the belt holster (which twists, thank you Moto) securely so it cannot fall off. With a simple thumb motion you release and flip the phone open. Great design.Here's a list of my favorite features thusfar:Themes - a grouping of settings for a particular location. Set the car theme to loud ring, voicemail notification, etc then vibrate only for like a theater or business meeting them. Much better than scrolling through ringer settings for twenty minutes.Speakerphone - fantastic quality, doesn't contain the traditional speakerphone echos. Most friends are not aware I'm using it (unless I'm driving, speaker + driving = noise central).Web-downloadable address book - nice touch, I can change business contacts info online using keyboard rather than search-and-peck phone typing.Java-apps - I downloaded a chess game for my phone, plus MSN messenger, and a grocery list keeper.Voice-activated dialing - make calls while the phone's closed. I say, &quot;Call Dean at home&quot; then it dials and puts me into speaker mode, opening the phone converts to a private call (or use earbud). Making calls (while it's closed) without removing from my belt holster - sooo convenient.Checking external emails - my i90c alerts me when I've got work or home email (and let's me preview).Web browsing - only six lines but that's plenty for catching my daily weather forecast, stocks, and headline news while riding the train into work. Favorites, shortcuts... you can customize your homepage too!Voice memo recording (three minutes), text memo, datebook, two-way messenging, call timer tracking, forwarding, and the list goes on. That's all of my review, time to play a game of chess with some guy in Chicago on my i90c! I'll win this time, I promise.
