The 7-inch tablet is the first Android slate to feature the Camera Awesome app.
The 10-incher is another moderate Windows 8.1 release in HP's latest lineup of slates.
The latest Samsung Series 9 goes extra-big, and the gamble pays off with the most portable and comfortable 15-incher you're likely to find. However, its high price and lack of higher-end features don't make it the best value.
If you ignore the ultrabook branding and instead think of this as a somewhat slim midsize, mainstream laptop, the 14-inch Samsung Series 5 is a fine example of the form.
