Summary: I purchased the E6430 several months ago. I used an E6400 for many years and absolutely loved it. It had such a great feel to it. Everything seemed really solid and well built on it. When I opened the box for the E6430 my heart sunk a little. I was disappoint. The build looks cheap in comparison to the E6400. The model I bought was top of the line, but the display isn't near as good as the E6400.
Summary: The weight/speed/battery life are GREAT. Worth every penny. However, the screen is the WORST possible. Remember your 10 year old VGA laptop? Yep, that bad. So bad I had mine replaced thinking something was wrong. Adjustments are ineffective and can only make things barely usable.
