Toshiba formally threw itself into contention for US tablets with the launch timing for the Thrive. Its dual-core tablet is now due to ship with Android 3.1 and should ship to Best Buy and other stores on June 13, more than five months after it was unveiled at CES. The Japanese company is counting on undercutting Apple on price by offering an 8GB Wi-Fi version of the tablet for just $429; 16GB and 32GB versions will cost $479 and $579.
