The backlit keyboard will be optional as I understand. This will be "extremely" useful for me. Have you ever tried writing something on your laptop in complete,or close to complete, darkness? Like in bed or in an aeroplane? It makes your eyes bleed after ten seconds...
Why didn't they copy the Thinkpad "thinklight" idea. Just put a small light in the LCD lid that can be turned on with an "FN" key combination and it lights up the whole keyboard without draining your power down. Makes typing in complete darkness a snap.
I agree on the "business" aspect. Improvments in the trackpoint would be infinitely more useful than a backlit keyboard. How many times do you use a laptop in near darkness?
Our company was originally going to get D610's but with the upcoming release of the D620, we are delaying our deployment of the new laptops until July. We were told the D620's were going to be released in April.
If we didn't delay our deployment, then through the 3 year life cycle of our laptops, we would have 3 models in circulation. By waiting for the D620, we will only have 2 models to support over the next 3 years.
