10. Axiotron ModBook with built-in WAAS-enabled GPS (Core 2 Duo 2.2GHz, 2GB RAM, 160GB HDD)
Editors' rating: 7.2
The good: Ingenious design, marrying slate tablet to bottom half of a stock MacBook; built-in GPS; Wacom digitizer for accurate input.
The bad: Screen is stuck in landscape mode; heavy; big premium over original MacBook cost; shorter battery life than the MacBook.
The bottom line: We're impressed with the engineering behind Axiotron's rebuilt, tabletized MacBook, but the target audience is likely very small, especially since Windows-based convertible tablets do so much more.
