Please recommend me what is faster between blackberry and samsung galaxy 3. I preffer the last one because has android
The S3 has far better spec than any BB, though the less resource intensive nature of the BBOS means a BB doesn't need as much power to remain as quick at opening applications such as contacts and emails and thus runs about as fast for general use.
Start to try and do anything intensive on both devices though and the S3 will wipe the floor with the BB.
Surprisingly people still do, it's just their the cheaper option in terms of smartphones but in terms of quality the OS can't compete with Android/Apple.
Also apparently the leaked Nexus 10 is not a final design (even though it matches the leaked user manual.
I certainly hope not, it doesn't look at all appealing to me. Although I can't remember the last mobile product Samsung came out with that appealed to me from a design standpoint.
