Agree with all the above. Previous platforms needed custom chips to provide support for features Sony thought were needed. This is the first generation where off the shelf is good enough.ignores the sea change in mobile gaming? Well then so does the 3DS. Perhaps both companies predict that there will be a large enough market for dedicated handheld gaming devices to justify launching a device?
Actually if anything, I'm slightly disappointed in the Vita. Its almost *too* off the shelf. Where is the amazing custom processor of the PS1, the insanity of the GS from PS2, or the CELL from PS3? Its just a slightly newer PVR chip than others have - you'll probably see tablets with that in this year or early next (doesn't mean you'll get the same out of them, or see the same games obviously)
Its the first console where we could literally see exactly the same chips in another machine. Actually, how standard was xbox 1?
Now SONY has to be a Software company providing Developer SDKs not hardware features to make their platforms attractive. Vita is a new platform with a lack of developer features....at least so far. The intellectual property lists for the Vita include Handwriting to text, Voice recognition and more but we haven't seen them yet. Also the unfinished Vita Browser is telling. The next 3 months will be interesting. Feb 22 may have many more HTML5 features in the Vita including voice recognition which is supported in webkit and by Netfront Access NX. UNIX (Vita is Free BSD Unix) webkit ports are supposed to have the webkit2 API done before March 28th.
