Should i replace my Motorola L6 for a Sony Ericsson W810i

Ok I have had my Motorola L6 for almost a year and a half but I am thinking of getting a Sony Ericsson W810i but need help justifying myself into buying it. I already have an MP3 player this would just be easier to carry around with me. I don't fully comunicate with people a whole lot but always have a bit of money to top up with. The main use i have for my L6 at the moment is an alarm clock which i could get a cheap one for that and it does drain the battery a lot on my phone even when i turn it off which makes me wonder if the L6 battery is up to scratch.
I really want the W810i but like i have said i need help to justify such a buy.

Please help those who own the w810i in showing how good or bad it is
