Query: Nice but wouldn't buy it again...

The Linksys WIP320 offers good sound quality but:- Battery weak; lasts an hour in speaking, you have to charge it always during standby to make sure you have enough power when a call comes in.- Had several situations where the phone made a reset by itself or didn't reacted anymore (so the battery had to be removed, then it would restart).- Can't join wireless networks which require authentication- offers just a few ringtones to choose from and they all sound horrible. There's also no way to load additional ringtones via the USB port- Somewhere "speakerphone" was mentioned... well, not that I ever managed to get that working.- Headset port doesn't work with every 2.5 plug headset.
