The Siemens SL45 is the first MP3-enabled mobile telephone we've received in our laboratory to date, but I'm sure it won't be our last. Considering how MP3s have changed the way we listen to music, the SL45 is taking this a step further to keep us 'listening' always.
MP3 playback may cut short the battery life of the phone to just three hours-more or less, but it re-charges quickly (about two hours), and it works well on all counts.
It's too bad you can only store up to just 20 minutes of music playback (40-45 minutes with 96Kbps encoding), so it would be good if Siemens could introduce a 32-to-64MB MMC swap plan in the near-future. Of course, a neck sling for the headset and a USB connection option for the SL45 would be useful also. But other than these suggestions, the Siemens SL45 MP3-enabled mobile telephone would be a classy-looking asset for any fashion-conscious mobile professional.
