iPhone is the safe choice, but expensive. Android has quite some good phones, but some 'misses' as well. BlackBerry seems to lose popularity by the day. Currently I own a Windows Phone (Nokia Lumia 800), which is not that popular either.
Personally I would advise a Windows Phone, but thats my taste. If you do so, be aware that a few apps are not available yet on this platform.
Has aanyone ever sent in their iPod for repairing? Is it worth it or in the end more expensive than a new one? I'm talking about my iPod classic with 60gb. It's 6 years old by now,but a new same one still goes for over 300 Euro. Repair or new one?
Probably not worth it - six years old, it'll cost you more to send in than just getting a new one. I know I was quoted originally $300 or so on an iPod that was worth around $400.
Have you checked out any second-hand places? Usually you can pick up gadgets and things pretty cheap (well relatively anyway) if you know where to look. I saw an iPod with 30GB hard drive going for $120. Was almost gonna pick it up at that price.
