Well... Don't know you but I use/need things that iPhone can not: - Use Gizmo Project (SIP) account to make VoIP calls when overseas - Use it as GPS device (I bought external Bluetooth GPS receiver for that purpose) Works great with free MaemoMapper! - Transfer/save/copy files easy with removable SD cards (and external USB reader makes this even more flexible.) - Upgradeable up to 32GB of memory as of today (2x 16GB SDHC cards are available) At the moment I use sinle 8GB card. - Play most format movies using Mplayer, without converting first to some other format. - Don't need to use iTunes bloatware (over 50MB!!! ) to "sync" my N800. - Play stream radio stations (Shoutcast... iPhone may work on this too?) - Connect my digicam and camcorder directly to N800 using N800's USB host mode. - Do video calling to home (using Gizmo) when travelling overseas. - Skype, though I do not use it that much. - I can purhcase extra batteries to swap if I need extended use time. Just something to start...
