The pocket powerhouse 
The New Gameboy Advance is a 32-bit (32 bit RISC-CPU + 8 bit CISC-CPU) portable system that is compatible with all current Gameboy games (well over 4000). The GBA takes two AA batteries which apparently has a max life of 15 hours. The GBA also features a bigger (40.8mm x 61.2mm),  higher resolution  screen and more buttons to press!
