LMAO...
as green says, E50 or 5500... for a 2nd phone you just want a smaller one...
E50 is great for lots of talking, the battery life is what every S60 should have...
5500 if you want to be outrageously different... aside from what green already mentioned, where else can you find a phone that plays like wii, gives you a flash light, measures the distance you have covered while taking a walk or riding a bike without the need of a gps (btw, it can also use a gps), great MP3 player as well???
and it is the only S60 with a curve like a waist of a young woman... its just so comfortable to hold that curve, just like a woman...
oh, but then you said texting, the 5500 might be tough for lots of texting, it is ok for like 10 or so sms a day, but not for those whose life revolve around txt...
