Nexus 10 is the SAME PRICE as a base ipad and the same specs.
Nexus 10: CPU: Dual-core A15, GPU: Quad-core Mali TS04
iPad: Dual-core A5 Chip (CPU and GPU combined, ugh)
Nexus 10: 2560 x 1600 (300 ppi)
iPad: 1024-by-768 resolution at 132 pixels per inch (ppi)
Nexus 10: 2GB
iPad: 512MB (actually had to look that one up on Wikipedia
There's more, but you can see (if you take your Apple blinders off) that the iPad isn't even in the same ballpark as the Nexus 10.
