I have been following your posts , you seem so obsessed with lag. One minute you marvel at the phone, another minute you complain about the lag. None of the latest smartphones seems good enough - all of it display lag at one point or another. I suggest you buy the iphone 4 without lag issues and no fragmentation problems due to different hardware. Is the lag so serious that it will affect your usability  - I feel you are taking your judgement to a microscopic level already. I watch the same videos as you have commented - is the lag so serious ???

And there is actually no point deliberating about all these unless you have a hands-on experience yourself. You have also to expect there will never be a "10" android phone - if such exists, the whole smartphone industry will be boring. Only Steve Jobs claim his iphone4 is the only best smartphone in the world. Nobody in the Android world ever dare make such a statement. It seems to be  a conspiracy among the manufacturers - that's how the manufacturers get customers to forever upgrading and changing to meet their needs

Lastly none of the manufacturers is forcing you to buy; if you don't like what you see/or read - just don't buy. No point agonizing - it is your money. Keep it for your studies which is a better option for now
