I had the pleasure of treating myself to a new phone recently. I had a lot of options, but I finally settled on a Nokia N95. It is a good phone, with good features, and I would recommend it to anybody who wanted more out of their not so smart phone, but couldn't quite justify the use of a PDA. I'm with Robert Scoble, though, I'd prefer to get an iPhone, but that won't be released in Australia until early 2008.
For more info on the N95 visit the NSeries website, it will tell you more about my phone than I can.
There have been a few issues with the phone in regards to the GPS software included with the phone 'Nokia Maps' and there seems to be much forum confusion as to what the deal is in Australia. Hopefully I can clarify the situation:
The maps take forever to download, so in the interest of being a nice Internet citizen, I have decided to begin sharing them on the ED2K network. Alternatively you can download it from me directly.
You will need something to open .rar files - I highly recommend WinRar.
To be honest, for the most part, Google Maps on the mobile is a nicer all round experience, but until it starts using the in built GPS, it is still a toy. If you want something to use in the car, go get yourself a dedicated unit, the N95 has better POI's but it still doesn't come close to the TomTom One XL.
Personally, I plan to use the GPS feature for bush walking, and Nokia provides an excellent route stat application called Sports Tracker. With it you can graph your movement, and save the results in Google Earth compatible files, XML, CSV. For this, the N95 absolutely rocks.
