However, the major drawback of this phone is the much too small internal memory of only 4GB. Included with the operating system you have anyway only ~ 2GB free, then the most important programs (for me Whatsapp, Ebay, Deutsche Bahn, Skydrive, Dropbox ...) installed one is jerk-twitch at ~ 1-1,5GB free space arrived. Those who want to now install one or the other game has its unit in no time to the top packed with information and have to start again to weigh whether a program is still needed or not.
You might think though, this problem could be facilitated by the memory card slot quickly and easily fix (after all, summarizes this theory maps up to a size of 1TB - if there were such as), but this is not so. On Windows Phone 8 apps can only use the internal memory, the card is only for media (music, videos, photos). An issue which should be resolved by Microsoft quickly.
Meanwhile, I have the HTC 8X, which has 16GB of internal memory, but no card slot. Personally, I do not need mind-boggling large memory in the smartphone, but that I have to start after 1 week already superior to what I want to keep and what I can not delete it.
In the price segment around the 250 you should look at the Windows devices at Nokia, the Lumia 620 has, for example, 8GB internal memory and even a Dual Core.
In my opinion, Microsoft should specify the manufacturer, the memory size of 8GB as a minimum.
