The new Nokia N91 is an iPod killer. In addition to its traditional phone capabilities, it also features a 4Gb hard-drive and the capacity to sync with iTunes and create new music playlists on the go. On top of that, it can also use wi-fi technology to interface with music docks and stereos.
Implications - It will be interesting to see if this ingenious phone will be able to pose a significant challenge to Apple's iPhone. Without a doubt, however, it packs some very useful hardware of its own. It's impressive to see how the iPhone is making other companies step up their game, and I look forward to seeing what the future of smartphones will hold.
