Just because your notebook or hybrid tablet has a touch screen does not excuse the lack of a touchpad. Your finger simply cannot replace the precision of a touchpad when it comes to manipulating the cursor. Acer’s Aspire P3 has an optional cover that doubles as a keyboard, but it lacks a pointing stick and touchpad. The MSI Slidebook S20 suffers from the same glaring omission. You’ll definitely want to plug in an external mouse — if you buy these devices at all.
The VAIO Duo 13 is another offender for a different reason. The 3 x 1-inch touchpad on this slider design is so small we found ourselves constantly bumping up against its edges. The touchpad is something you shouldn’t even have to think about, and here, it’s a chore.
