Nokia teamed up lately somewhat heavy were concerned what quality materials and workmanship. At E66, Nokia has once given, however really bother and besides the good inner values (S60, HSDPA, GPS ...) built especially good housing. The material is high-quality, partly metal, the slider mechanism very well and precise and, above all, the keyboard is very accurate to use and once again a reference. Especially the lower slider part using the numeric keypad is very well resolved with a little distance from the upper part, to short but crisp tactile feedback, just outstanding. For a slider that E66 is a real flatterer very thin and thanks to the material used. Besides Cam (3.2) and UMTS / HSDPA, and Wi-Fi also GPS part of the equipment. Thus one is currently more prepared than adequate. Also fitted is a sensor, so that you can screen content gets displayed across the rotating the phone. Due to the low overall height, there was not enough for the usual 3.5 jack (mini jack), but only for 2.5 (Micro-Jack). Per adapter but anpassbar.Oder equal use a Bluetooth headset because A2DP is also supported. The award goes to the abundance of features, but also because of the quality offered in order. The E-series seems to be already processed with better than Nokia ale other series (including N-series). For the E66 applies: buy recommendation!
