Once the leading maker of laptop computers, Toshiba hopes to thrive again with the aptly named Thrive Tablet. The three 10.1-inch touch screen models, expected to ship in mid-July, differ only in the amount of internal storage: the TOAT105T108 with 8-gigabytes ($429.95), TOAT105T1016 with 16GB ($479.95), and TOAT105T1032 with 32GB ($579.95).
