I saw this billboard advertisement by Microsoft for their new Surface Pro tablet, and first of all I totally disagree with the whole 'tablets can replace laptops' rubbish, but I don't want to go off on a tangent about that. What struck me with this was that the catchphrase does not make any sense grammatically, it is like it was a sentence but for advertising sake they have shortened the sentence to 'give it a nice short ring to it', but it just sounds wrong. It should have said 'As powerful as a Laptop, but lighter than air', the two words do not make too much extra space and the sentence runs much more smoothly. Or a shorter alternative Powerful like a laptop, but lighter than air, this cuts out the additional 'as' at the beginning and make more sense than the original. And if they did not want the sentence to span the whole length of the billboard edge to edge they could have always re worked the layout. They could put the first part at the top, then the tablet in the middle and the second part at the bottom. This also sandwiches the tablet and emphasized its slim size. This could have been easily done if they got someone to look at it with fresh eyes to pick out these issues, or if they did not rush and if they did some thumbnails of different layout options. This is an example of bad practice.
