bar types, slide-ups or flip-tops?

I finally sold my old 3660, so I'm looking for another cellphone. The N-series is very popular nowadays, and so are the other big, bulky PDA types, but their price ranges are way out of my budget because I don't believe in saving my salary for a big purchase of 10thousand up-- think of all the other things I can buy for that amount! I rather like the Motorola Razr series (v3, v3i, v3x, etc.), but someone told me this series has battery issues. Someone offered me a 6230i or a 3230, but after the bulky 3660 I realized I don't really go for the big, bulky phones. Someone also suggested the 5500, but I find myself gravitating towards the flip-top phones like the V3 Razors, only I don't like the square ones. I prefer rounded flip-top phones like the Nokia 6101-- in fact I really, really like the 6101, but it doesn't have a memory card!

How about you? What type of cellphone do you like--- the old-fashioned bar type, the slide-up type, or the flip-top type?
