Acer Aspire S5 Ultrabook Review: The Steady March of Progress
 

First generation technology is seldom perfect, and the fruit of Intel's ultrabook initiative was no exception. While vendors came out in force with some fairly impressive pieces of hardware, these first shots at the form factor all came away lacking in some way. Be it thermal performance, general performance, build quality, or display quality, no matter where you looked you were forced to make some kind of compromise. Intel's Sandy Bridge architecture wasn't horribly suited to the tasks, either, but it was also clear that at least another generation of processors would be more ideal to the increased thermal constraints of the platform.
