I use Samsung B2710 when I go skiing. This season this phone has been subjected to some pretty tough weather conditions, such as -20C/-4F, and it kept working as if it was under a warm Mediterranean breeze.
As a smartphone user however, it reminds my why I chose iPhone in the first place: B2710's menu is old school, getting around the phone's limited options is a pain, typing a long message is difficult, etc etc.
I would not recommend B2710 for daily usage (buy a smartphone instead!); although it supports emails, facbeook, etc. it does not have WiFi so you have to use all of those services via 3G. On the other hand if like me you are buying it as a second phone, lack of WiFi may mean roaming charges. Beware!
If it wasn't for the lack of WiFi, I would have given this [holiday] phone 5 stars.
