First up the Huawei G510.
When I first read the Cnet review I wasn't at all surprised, The stock ROM on my G300 was bloated and sluggish and when I ran ANTUTU the benchmark score was significantly lower than it is now with CM10 as well as the picture quality from the camera showing significant improvements with the jump to Jelly bean from Gingerbread. Now with the bloated software that Huawei supply as standard then I can believe that the performance is slow and lack luster but as soon as CM10 is ready for it I cant see any reason that these problems would be ironed out........ As for the comments on design, well its not a looker but that is way down the priority list for me. At £130.00 I dare you to find an android powered device that is better.
Now for the Big Boy...... The Asus Fonepad
Having read these reviews I know which way i'm heading and i'm sorry to say Huawei it is not your way.
