“I have been testing the G1 extensively, in multiple cities and in multiple scenarios. In general, I like it and consider it a worthy competitor to the iPhone… But the two devices have different strengths and weaknesses, and are likely to attract different types of users.”

Mossberg’s GPhone positives:

    * Keyboard.  Keys too flat and weird bulge in body, but at least there’s a keyboard.
    * Removable battery.
    * Expandable memory.
    * Cheaper. Phone $179 vs. Apple $199, Data plan $25 vs $30.
    * Equally slick software.
    * Better “desktop.”
    * Higher-res camera.
    * Much easier to make telephone calls.  Imagine that.
    * Key features that Apple bizarrely still omits: cut-and-paste, MMS,
    * Ability to legally unlock and go to another carrier (with fat fee)
    * Longer-lasting battery.  A whole day. Imagine that.
    * Slightly longer talk time. (5 hours, 19 minutes more)
    * Wicked cool compass that orients you on map.

Mossberg’s G1 downsides:

    * Chunky brick.  20% heavier, 30% thicker.
    * Puny memory. 1 gig, one eighth of iPhone.
    * Only 128 mg memory for third-party apps.
    * Too much lock-in with Google services (contacts, calendar)
    * No Microsoft Exchange support
    * Can’t sync with PC or Mac
    * Overall, interface inferior (no two-finger zoom magic)
    * No onscreen keyboard, so have to use bulky external keyboard.
    * Weak music player, no video player
    * T-Mobile network coverage sucks.
