Laptops and Tablets, what are you views?

Have been looking for a new notebook or laptop computer for over a year now. I am tired of this old HP dual core model I have. It is heavy for one thing and the battery is what weighs the most. The battery does not last long any more and I do not want to buy a new one for this old portable computer. I have been to the brick and mortar stores and looked at and lifted many of them. I am keen to Lenovo as I like their styling. Especially after having bought the desktop model a couple of years back and loving it without having any problems so far. So, with that, I welcome anyone's comments. I am looking forward to the new models soon to be out too. I have read where the new 4th generation processors work on 1.4 or 1.5 volts. That equates to a lot less power consumption and longer battery time. It would be cool to do tests of different laptops and their battery lasting power time. Are there any manufacturers out there who would care to donate? Just get in touch with me here. I am ready to go! Oh, tablets. I didn't mention anything about tablets did I. ;)
