Most reviews point towards the OS being very smooth with little to no lag. Its Android that makes you think you need the high specs, when you don't. This OS runs HTML5 rather than Java so much more efficient than android. Windows Phone can also run just fine on a slightly higher CPU but with same RAM, and higher res screen. If they had added better specs like you suggest then it would be £100+ which people don't want. I wanted a cheap device to trial an OS, and ZTE delivered. Hopefully that chip is good for a reasonable OC to maybe 1.2GHz
