We've used netbooks for several years and it has the same computing power as many desktops and laptops from the same era. Photoshop even runs well on it.

We have owned 2, an Acer with a 16 GB solid state drive, and a Toshiba with a larger conventional hard drive. The Acer was very slow and would not handle many programs. The Toshiba on the other hand is fast and just as durable with about 12,000 miles in a rear pannier and still going strong. The 225 GB hard drive will handle programs like Photoshop without any problems. It has 3 USB ports and an SC card reader. We thought about tablets, but we often work on projects while on the road. We have even produced monthly newsletters for an organization we are associated with while on the road. On a recent tour we downloaded 10 GB of pictures to the laptop as backup for the cameras' cards. We usually backup the pictures to large capacity thumb drives. The lack of USB ports as well as the smaller keyboard make the tablets less convenient for our needs. However the weight difference makes switching to a tablet appealing.
