In my opinion, the advantages and recent improvements of BB10 come with this device even clearer advantage. It starts with a larger, clearer stroke and ends with a design optimized for mobile pages to browse. When Z10 I often had the problem that fonts are ran out from the side or illegible due to the annoying line breaks. Clear benefits will also find the Z30 from other 5 'smartphones. The Z10 has a relatively unusual form factor.
When Z30 was placed on the optimization and the "Ausreizen" form factor in relation to the display size value. At Z10 there was still plenty of need for optimization.
What has struck me the Z30 directly, the battery lasts almost twice as long in spite of the large display. Thus, I come without loading loose 1-2 days to make ends meet (my wife also equipped with Z30, comes out even longer). When Z10 I had now and then the problem is that it had to be urgently evening loaded with constant use.
Media playback, tone and BBM (especially the video chat) are connected to the part simply ingenious and very pleasant in terms of acoustics and representation. Here the 5 "display (and the tips Grafikprozessur) its advantages. Functions and the last mentioned BB10 optimizations such Miracast let the Z30 wonderfully connected to the home theater.
Everything else has been said, only one more thing: It is currently the best smartphone ... ;-)
