I've just upgraded to this after having a Nokia 6300 for a while.
Firstly the positives:
~Good Resolution Cam (5MP + Flash)
~Fairly Easy To Control
~Very Customisable (e.g. themes, mp3 tones, navigation)
Some of the Negatives:
~Seems Slow and Sluggish When Typing or Browsing Folders
~Cam takes ages to take a picture
~I've had trouble connecting it to a Vista PC even after downloading the latest version of software from samsung.
All in all a very good phone, was recommended to me and i am quite happy i went with it although some things seem slow when using the phone such as txting which does annoy me but is something you have to get used to. Some of the menus can be confusing as well as some items arent where logic dictates them to be. Would still recommend despite my petty annoyances with it.
