The “gPhone” is going to be nothing short of unrevolutionary 
All a load of hoo-hah over nothing IMO. It may be a great platform, or not, but history is littered with failed attempts to sell a new, greatest, bestest, most-amazingnest OS to developers.
Whatever it is - phone, OS, concept, whatever - the one thing I am certain of is that it represents a threat-to-anyone-but-Apple. If I was President of the Windows Mobile division, or Symbian, or RIM, I would be extremely worried indeed, but Apple has nothing to lose and everything to gain from Google’s foray into this market. Google will be the Ford of the mobile world, Apple the BMW. There’s room for both, and both will prosper - they are broadly non-competitive and both produce excellent products - but the mass-market competition for Google had better watch out: if it can produce a good platform, and more importantly a good SDK for developers, Symbian and Windows Mobile are toast.
