Pros: Battery life, speaker phone, durability, reception, voice calls
Cons: rather bulky, loud keys, SLOW INTERNET speed

I've owned the SCP 4500 before, and I really like the following features:

-When someone calls in, the phone says "Incoming call!" Even after 4 years on the market, the SCP 4000 series still turns heads! It's also distinguishable from other phone with their generic ringing.

-Battery life. Like the SCP 4500, the battery life is extremely long (about two weeks standby)?

What I don't like are:

-For some reason, my car power adapter does NOT work with the existing case for the phone (the case is too fat for the plug to fit in). I have to remove the case just to plug it in to my car adapter.

-I can't see the screen in direct sunlight. I have to use my hand to cover the screen.

-the 3G internet service is SLLLOOOOOW. I used to have wireless web on my non-3G phone, and it was much much faster. I'm not very pleased with my "high speed" internet service, although it looks cool.
