Toshiba's Portege R705 is an unexpected addition to the company's ultraportable range. Based on the Portege R700 unveiled as part of Toshiba's 25th anniversary for notebooks, the R705-P25 is a Best Buy exclusive with an MRSP of $889.99 but a street price that scrapes in at under $800. That makes it the cheapest Portege to date, and Toshiba would like us to remember it's also the lightest 13.3-inch notebook with an integrated optical drive (outside of Japan, at least). Light in the bag and light on the wallet: is the downside lightweight performance? Check out the full SlashGear review after the cut.
