Samsung Electronics has big plans for its tiny Q1 ultramobile PC. Despite a less than warm initial reception for the diminutive PC category by analysts, Samsung said its Q1 UMPC has exceeded its expectations, particularly for businesses. And now it’s raising the bar. Samsung, which had not sold a Samsung-brand PC in the United States for several years before the May 2006 launch of the Q1, expects to announce soon at least one deal to sell quantities of the $1,100 UMPC to a corporation. Meanwhile, depending on the success of the device, its future plans include at least one Q1 follow-on and possibly offering Samsung-brand notebooks again in the United States.
