Probably the PSP or the PS Vita, Cherie? Those were both pretty poor performance-wise but the biggest handheld Sony consoles.

This is interesting if it really does have a high performance... Nintendo have been floundering for far too long with hardware that was last seen as acceptable in 2010, and just seem to refuse to adapt and put out a Switch that can actually hold storage or run games that look good. If Valve can edge them out of the handheld market they might actually buck up their ideas.
