Sony brings its own design touch to the tablet sweepstakes with a tapered design reminiscent of the MacBook Air. Unlike its Android competitors, Sony doesn't offer models supporting cellular data, but otherwise the specs are almost identical: dual-core, 1-GHz Tegra 2 processor, 1,280-by-800 display, 16- or 32-GB flash, and the standard Android software stack. Unlike the other large-screen competitors, Sony does undercut the Wi-Fi iPad by $100 and also promises an Ice Cream Sandwich upgrade.
Biggest pro for enterprises: Android 4 upgrade will be available. Optional add-on battery pack (may need due to the next item).
Biggest con for enterprises: No cellular data, smallest built-in battery with shortest run and standby times.
Notable differences from rivals: Least expensive Wi-Fi device. Tapered design may appeal to some users.
Pricing: Wi-Fi, 16/32/64 GB -- $399.99/$499.99/–. Wi-Fi + cellular, 16/32/64 GB: not available.
