The Nokia N81 and N81 8Gb are two highly sophisticated models with beautiful look to them. with the N81 8gb there is no need for a memory card so it has none while the N81 has a slot of its the users preference on which he likes internal memory or a memory card to store his/her data. personally i think its faster and your music/motives/pictures will load up quicker with internal memory with my experience using computers this is always the case.
Both models are QuadBand so you can use them around the world with GSM carriers. Both Have WLAN and 3G for all those who enjoy the net and high speeds of it. Also Build in Bluetooth and Usb for data transfer between computer and phone or phone to phone. I'm not impressed with the 2mp camera but with everything else build into the phones (see below) its not too bad. Over all these two should do well with users enjoying their features and all they have to offer with games and more.
