What are the best all purpose <13.3" laptops for kids (<14 years old) for under $300?

The 2.16GHz Celeron N2840 processor paired with 2GB of RAM provides lackluster performance. In Geekbench 3, it scored 1694 (below the HP Steam's 1804 score, also below the EeeBook X205TA's 2212 score).

However, it performs admirably in OpenOffice testing - 25% faster than the EeeBook X205TA and the same as the HP Steam 11. It also manages to transfer files quickly (compared to the competition), at 53 BM/s (EeeBook X205TA achieved 41.3MB/s, and the Steam 11 achieved 44MB/s).
