The iphone is 'limited' in that it lacks a few fundamental features that could make it really useful, such as effective Bluetooth capability with data transfer, the ability to use it as a portable storage device, optical connection, storage expansion via SD card or similar, and a front mounted camera.
I have never needed Bluetooth to transfer any kind of data; anyone wants something that's on my phone I'll email it.
Mass storage device; well, I could use my phone, I've got Airshare, so copying via wifi is what I'd normally do, however, there's a neat little jobbie that plugs into the dock that will take an SDHC card up to 32Gb should I want to remove data or copy data when away from my computer.
FM radio; who the **** wants a shitty FM radio on a phone? They don't work away from a large urban area, hell, my local FM transmitter barely reaches three miles out of town in the car, and wouldn't give a signal on my old Nokia at the back of my house when I can see the transmitter from my bedroom. Idiots keep bleating about iPhones needing FM Radio, but why? What's there you could possibly want to listen to? I can listen to any BBC or independent station from any part of the UK, I listen to KROQ in LA, CBC Radio 3 in Canada...
I've even listened to a radio station from the Faro Islands. Try doing that on your crappy FM radio.
When Viewranger becomes available for the iPhone then not only will you have OS mapping available but mapping for lots of European countries, plus you can get Geo Survey maps for the whole USA for free, all installed on the phone so data roaming isn't needed. FWIW, I use Memory Map Free on my phone, so I've got the whole UK to 1:1million and 1:250k, and a big chunk of 1:25k from Marlborough to near Bristol plus the Forest Of Dean, for less than £20 so far. I love
OTA (over the air) map downloads. Then there's all my ebooks for when I can't be arsed to browse the net, or listen to some of the 1100+ songs on here, or listen to Canadian indie rock or whatever.
Yeah, I guess the iPhone is a ‘toy’, in some people's opinion; probably about the same as my 17"laptop is
seeing as how the phone gets used several dozen times a day, compared to the laptop sitting under the TV for weeks at a time. Whatever. If all you want a phone for is to play dumb games, then I guess an iPhone is a toy. However
mine happily replaces most things I use a laptop for, so I tend to think of it as a useful day-to-day pocket computer with always on Internet capability.
