It is quite time for Nokia to announce its second generation of Booklets.
The things I'd like to be upgraded/updated in Booklet are:
- true SATA interface - will make Booklet fly with SSD
- 2Gb of RAM by default - will help Booklet fly even without SSD

If Nokia would introduce following features, "Wow factors":
- touchscreen (possibly multitouch) - would help a lot when Booklet is used as GPS in a car.
- Pixel Qi display (or similar technology) - would help battery life
- enabled voice feature of 3G modem and functionality integrated into Nokia Social Hub / Ovi.
I see no need to install more powerful CPU (SSD solves majority of speed related questions), if battery life goes down. The same applies to GPU (GMA500 is enough if its capabilities are fully utilized).
Many producers of Notebooks offer several preconfigured models of Notebooks with ability to have customized versions for extra fee. Nokia could go the same road, and in addition to several colors, add several preconfigured models:
- 2Gb RAM - 250Gb HDD - OLED - $550
- 2Gb RAM - 160Gb SSD - OLED - $800
- 4Gb RAM - 300Gb SSD - Pixel Qi - $1200
These models could be subsidized by Cellular carriers (like AT&T did with original Booklet 3G) to reduce upfront costs even further.
With each of the models having 12h of battery life and touchscreen there would be no competitor out there. Even Apple Air Second Gen would cry

Nokia Booklet 3G upgraded with Intel x18-m SSD and Fedora 13 (Linux) as main OS
