The battle of tablet has just begun. There will be a lot of companies who are currently developing/ manufacturing tablets. These tablets are going to roll out start end of Q1 to the end of the year. It is difficult to believe the tablet will die down unless it is meant the growth be slowing down. I am still skeptical of slow growth. Maybe, the discussion and talk will be slowing down. ;)
The LED lighting market will continue to grow, I believe, as manufacturers will push to make offerings more price attractive.
The Holy Grail of LED lighting is simple incandescent light replacement at a reasonable price.
A significant trend would be the adoption of low DC voltage distribution and the subsequent ease of installation, but I expect more of that in 2012.
As to Tablets, over a dozen makers are throwing offerings into the ring in 2011, and the ensuing buzz "die down" probably won't happen in 2011, given the success of both the iPad and the recent Samsung Galaxy Tab. Both prove a market segment exists that most likely will grow, not shrink.
