I have the unit for about 6 months in use, and do all sorts of things with it. In addition to the call incl. Video telephony, and SMS'en MMS'en I use it extensively on the Internet, listening to music incl. Audio books (4GB memory card), to navigate through the freeware NAV4ALL with a Bluetooth mouse and to manage my GMX eM @ ils via the integrated email client and on the E-Plus solution "Surf & Mail" incl. 5MB Datenflat. About a new savings banks Software (JAVA), which can be transmitted via the Sparkassen pages directly downloaded to the phone, I use the phone even for the Internet Banking. For surfing, I use the Opera Mini browser, which compresses the amount of data and reliably allows all sorts login's, which often does not work with other browsers. I hear music wirelessly via Bluetooth to the SE Headphones HBH-DS980 and the SE box MBS-100. I've been using the device so very intense stimuli and the opportunities available and to this day am fully satisfied with the performance of the device. The W890i runs absolutely fast and reliable. Very rarely it is me crashed before, then but always raised within one minute of alone again. Track ID is also a great thing that I always use when the radio times runs a song and I want to know how he is and who sings it to load it to me at the first opportunity on the net. I am always fascinated by the different features of the W890i. So also from the multi-tasking ability of the W890i, which easily allows z. B., when listening to music gelichzeitig nor an SMS or MMS to write and send to etc. By the way, the device is also processed top, looks in Mocca Brown Class and fits into a shirt pocket, which is important for me as a man, because we drag around with us any handbags ;-) If I use the device active, the battery needs to be charged almost every day, but that did not bother me. If you use it normally, the battery should last up to 3 days. The reception is absolutely ok, even if the display shows only 1 or no more bars. It seems to me as if the display very fluctuate, thus affecting the voice and reception quality but no adverse effect. Great equipment, strong buy recommendation.
