Nice slider phone, wanted a change from the bricks and flip phones.  Bluetooth is great, and the Samsung PC Suite (free download from Samsung) lets you edit your contacts, upload ringtones, and just about anything else you want to do.  Battery life is great, about one week between charges.  The speaker is not the greatest quality, so a headset is recommended.  Cingular did not bundle a headset, so that's extra.  Interface is intuitive and functions are easy to figure out.  Speakerphone sound quality is only marginal.
