I think you are right. I believe that we are heading for a three screen future. Mobile, Cinema and a third screen in which the market is going to be a bit split up between tablets and laptops depending on what you need. All these things will be integrated into one mobile PC unit for most users (just switching screens not your profile or software, probably cloud integrated). Why do people keep listing the Acer Aspire as a great laptop is beyond me. Acer stuff is not quality, it's got some bang for the buck but they also are on the poorer end of the reliability spectrum. Just helped my Mom pick out a new laptop. Got an Asus with all the goodies you might want for a light/moderate computer user for $400 bucks. It's amazing what $400 dollars can get you now a days, decent CPU, a lot of ram, HDMI, multiple USB ports, Bluetooth, integrated graphics are more than good enough for a non-gamers.
I'm part of a pilot program at my job testing out a new laptop that we're supposed to use "in the field," which means to make presentations at meetings. The problem is, nobody wants a "presentation" on a screen in the types of meetings I go on. There's usually only 2 -3 people involved and an old school paper deck works perfectly. I also have a company issued iPad, that could be extremely useful with digital contracts and to access internal data etc, but our legal department thinks the Ipad is too compromised to handle such things. -Not sure why. It's amazing how large organizations can be aloof regarding the right computing products for their employees. -We still cary blackberry's for crying out loud.
