[citation][nom]Hanin33[/nom]actually, only a few companies do the R&D, all the rest are rebranders or do minor physical layout changes to make their products appear different from the rest when they're exactly alike. you see this in the video card sector. incremental upgrades is the name of the game, folks...[/citation]
