Reliable and with a pleasantly-easy handling

Plus:
1. All buttons are accessible and only a few additional
2. The radio remains stable, even with obstacles
3. The handling is the same be-cross-bar
4. The practicality is clear and the device noticeably easier, many processes
5. The battery lasts very long
6. The touchpad is reasonable designed: scrolling is easy
7. Meanwhile Uneven surface makes cursor movements precise

Minus:
1. Multitouch gestures are desired fantasy, down to the zooming. While this is OK, but not a plus point
2. The arrangement of the lower keys (Ctrl, Alt, Alt Gr, Win) can be safely re-think (model i28)

Result:
7-2 = 5 star, but
1 star deduction,
because I was not quite satisfied with Touchpad and arrangement of the lower keys after 1 week and ordered as a reference the i28.
Touchpad and arrangement are therefore to be weighted more.
