After seeing the iPhone 5 keynote and looking at all the review videos I actually really wanted one, but I went to a phone store earlier today and tested one out and I have to say, I wasn't really that impressed. It was actually a shock to me to see how boring it was. I'm currently using an iPhone 3GS and when I messed around with the iPhone 5, it actually felt like the EXACT same phone. Obviously the screen was bigger and it was much faster but I couldn't believe how much it felt like my iPhone 3GS. I thought to myself, ok if I upgraded to this phone, "how would I use it, and what would I get out of it?" and all I could think of was..
Text messages - Exactly the same on my iPhone 3GS
Phone calls - Same on my 3GS. Maybe calls are better quality but I really don't spend enough time on the phone to care.
Camera - I would enjoy the superior camera, but I already have a decent digital camera so its not enough incentive for me to upgrade.
Browsing the internet - The screen is bigger so I can see more content, but I really don't find myself craving for that on my current iPhone so I don't think I'll care much. Web pages will load faster but again, it doesn't bother me enough on my current iPhone for me to care. LTE download speed would be nice but because I live in an obscure town I wouldn't expect to get any coverage or decent speeds.
Navigation - I already have the new maps system on my 3GS and the coverage is terrible in my area. As for the 3D maps, well when I tested it on the iPhone 5 I found it to be just as useless as I expected. Who is really going to use that feature to find there way around? It's so much simpler looking at flat maps. So yeah I don't care for 3D maps.
Siri - I would use Siri if I had an iPhone that supports it, but from what I've heard it gets boring really quickly so I can live without it.
Apps/Games - I'm not much of an app user to be honest. I only have about 8 apps installed right now on my 3GS and they all run just fine as well, so I don't think the extra performance you get on the iPhone 5 would matter much to me.
Email - Same as on my iPhone 3GS
Weather - Same as on my iPhone 3GS
Reminders & Notes - Same as on my iPhone 3GS
