When compared to Motorola’s commercialized Lapdock, the LightPad sacrifice does have several noteworthy drawbacks at this time.

First, the LightPad concept doesn’t present oneself users a trackpad. Though a nearly full-sized or full sized keyboard is part of the package deal, users may need to tap on their phones to control certain elements and retreat to the keyboard for typing, presenting the total package as an incomplete netbook or laptop replacement.
B, there’s no secondary OS like Webtop to take advantage of the extra television real estate. LightPad merely just mirrors the manifest on the user’s phone.
And third, as the device uses a pico projector, brightness of the presentation may be an issue. When the rear-projected 11-inch laptop concept is being old, brightness will be less of an issue as the smaller screen can display brighter images. However, when projected to a larger sift–like a 50- or 60-inch display, brightness will be a bigger issuance as a near-dark or completely darkened room will be needed to have a detectable and clear projected image. Pico projectors lack the brightness that larger, bulkier projectors can give because the total package comes in a smaller footprint and is often battery powered.
