Asus has recently updated their Transformer Book Series with a new model, the T100HA. Based on the promo video it’s definitely looking pretty spiffy! It’s running Windows 10, not Android so be aware. The key selling point is the reported 12 hour battery life which is likely under ideal conditions. It’s made of aluminum for extra durability and still maintains a great price at just $299. Asus perfected the small yet full sized keyboard designs on 10-inch laptops with their Eee PC. If you’re looking for a solid 2-in-1, the Transformer Book is worth looking at. The early customer reviews so far are averaging about 4 out of 5 stars with a lot of people mentioning the great battery life.
