The N81 was marketed as an entertainment device focused on music and gaming.[1] It was the first device that came preloaded with the N-Gage 2.0 gaming service in 2008 (albeit in public beta), and it features two dedicated gaming keys that can be used for N-Gage games (this would later also appear on the N96,[2] N85[3] and 5730 XpressMusic[4]). During the launch of N-Gage 2.0, the N81 was specifically chosen by Nokia in advertisements. It was also much marketed as a music-centric smartphone and was one of the first to support the Nokia Music Store service.[5] It has stereo speakers that are considered to be very loud.[6] Several reviewers have claimed that the N81 has, much like the older Nokia N91, a very high sound output quality and therefore highly suitable for audiophiles.[7][8][9][10]
The four-way silver-coloured D-pad below the display also contains a new capacitive sensor called the Navi wheel, which allows scrolling in the S60 gallery and music player applications by 'stroking' the key, in a similar manner to the iPod click wheel.[11] It is a unique feature that rarely appears on mobile handsets.[12] The Navi wheel would later also appear on other Nokia Nseries handsets: N78, N85 and N96.
Other than these the N81 has more modest specifications compared to the Nokia N95, with a 2-megapixel camera, lacking both GPS and HSDPA, and weighing 20 grams heavier.[13] However the N81 did have an ARM11 369 MHz processor, the fastest on a Nokia device at the time.[14] The Nokia N81 notably features a sliding spring-loaded physical keylock on the top of the device, located next to the 3.5 mm jack.[15] It is the first Nseries device that swapped the miniUSB port in favour of microUSB.
A variant called N81 8GB with 8-gigabytes of internal flash memory was also announced at the same time. This version retailed for 430 euros before taxes, 70 euros more than the standard version which requires a microSD memory card to expand its 12 megabytes of storage.[16] N81 would be succeeded by the N85.
The Nokia N81 had a lower sound output compared to the N91 due to the release of the new firmware version. According to Nokia, they must follow an international standard wherein a device's initial or default volume must be set too low to cause any damage to its users.
CNET found it buggy, slow, and badly designed.[17] S21 gave it 3/5, praising its feature set, while again criticising the "plasticky" design.[18] However its musical capabilities have been highly praised.[13][19]
