While the Acer Aspire One 751h and Gateway LT3103u both have 11.6 inch displays, which makes them larger than your average netbook, they also have slow processors and low price tags, which means they have more in common with your average netbook than with a fuller featured 13 inch or larger notebook.
Tech Report has taken a detailed look at these two models to see how they stack up against one another. The short answer? If you value battery life over performance, go with the Acer model. If you want a bit more processing power and you’re cool with 3-4 hours of battery life, the Gateway may do the trick.
Both models have decent keyboards and high resolution 1366 x 768 pixel screens. They also both ship with Windows Vista instead of XP. But the Acer Aspire One 751h has a 1.22GHz Intel Atom Z520 CPU which uses less power than the more common 1.6GHz Atom N270 CPU. The Gateway LT3103u, on the other hand, has a more powerful AMD Athlon 64 L110 CPU and ATI Radeon X1270 graphics.
