"Hey, HP: you're far from the only one who can play the ridiculously low-cost Windows laptop game. Acer has unveiled the Aspire One Cloudbook 11 and 14, a pair of thin-and-light Windows 10 portables that promise a 'real' PC experience even if you're on a shoestring budget. They respectively cost a mere $169 and $199 in the US (a good $30 less than HP's Stream 11 and 13), but still manage to pack 1.6GHz Celeron processors, 2GB of RAM, full-size keyboards and expansion that includes USB, HDMI and SD card slots. Neither is going to be a screamer, then, but they may do the job if you're looking for a back to school system that's just good enough to handle your class notes and reports."
