1. wrist watch phone
1.1. pros:
1.1.1. It usually comes with a Bluetooth headset in the package, making it almost usable on a daily basis It’s easier to see if you have any missed calls or SMS messages A watch phone is always in reach, so you won’t miss a call or new message (this can also be regarded as a weak point, in case you don’t want to be reached). The alarm function will also be really loud as it’s closed to the ear, so you won’t fall asleep anymore in the morning when you have to go to work.
1.1.2. You get it all, a cell phone, mp3 player, video player, digital and video camera.
1.2. cons:
1.2.1. A watch phone’s size is much bigger than a normal wrist watch, making it not a fashion statement and hard to match with your clothes Because it weights almost as much as a phone it’s hard to wear it all day long, and your hand gets tired after a few hours The screen is very small, lacking precision so that many times the menu options are hard to access, even with the stylus. Every watch phone uses its special operating system, so not much of support here from software developers, so even if you can install additional applications the offers is very limited.
2. Nexus One
2.1. Pros:
2.1.1. 1.)The Nexus One only weighs 130 grams and is 11.5 millimeters thick. 2.)Video can be played for well over 3 hours over Wi-Fi from YouTube in H.264 (Baseline 1.2). 3.) The screen will self adjust brightness 4.)Nexus One comes out of the gate with a beloved 5 megapixel snapper with flash. 5.You can assign your Google Voice number to the phone, and use it to make all outbound calls and text messages.
2.2. Cons:
2.2.1. 1. choice of coloring- we would have liked to see something a little more consistent as opposed to the two-tone 2. no physical camera key -- had some real trouble with those four dedicated buttons: consistently accidentally tapping them while composing an email or text message, or missing them when tapping a little too low. 3. color balance and oversaturated and cannot be seen in bright light. 4. tiny loudspeaker - unpleasant for conference calls. 5. the soft keyboard -- while better than previous models -- can still be inaccurate. http://www.engadget.com/2010/01/04/nexus-one-review/
