How about buying windows phone 7.8 now? Tell the truth.

First of all, I use an 820.

No, you misunderstood, of course wp8 is better, and not a little bit better:

At the same time, support Multi-core CPU, backward compatible, supports SD card. . . These are beyond the reach of 7.8!

There are a lot of bad things, but I believe they can all be fixed with updates: call-like call function, gravity sensor switch, vpn support (including the inability to customize the IP address of WIFI), and the trouble of group text messaging , contact management is not as good as Symbian S60 (at least I think so), applications cannot be installed on the SD card (Microsoft is actually right about this, it greatly reduces the probability of application errors), and the volume is unified and not separated (not as good as S60)

The above shortcomings are basically all present in 7.8.

Is it a bargain to buy a 7.8-inch mobile phone now? For example, the Lumia 800 with excellent workmanship and materials is only 1500, Radar and Omnia W are only over 900, etc. . .

The wp8 mobile phone is actually quite worth buying. It’s worth paying for the dual-core, high-resolution screen (920, 8x), new platform and new software!
