John Gruber at Daring Fireball:
Those who prefer Android, Iâ€™m sure, donâ€™t see this as a big deal at all â€” let â€œthe marketâ€ determine in what order these buttons should be. Those who prefer iOS find it appalling â€” Google should have done the work at the outset of determining the one true order for these buttons.
By this Gruber means:
- Back, Menu, Search, Home on the Nexus S.
- Back, Menu, Home, Search on the Nexus One.
- Menu, Home, Back, Search on the Samsung Captivate.
- Home, Menu, Back, Search on the HTC EVO 4G.
All four have different Android hardware button orders.
