The Booklet is a great laptop if you have a certain feature set in mind. Raw power is not that great, it has an Atom Z chip with only one gigabyte of RAM. The GMA500 plays back video buttery smooth and the ports and screen leave nothing lacking. The laptop came out a year and a quarter ago now, so in the PC world it is last generation.
I found that adjustments are needed to make this laptop shine. Mainly adding in a solid state drive and upgrading Windows to 7 pro. There are also 3rd party GPS drivers that work better, available on the Nokia product forums. After these adjustments, the laptop is totally solid state and much more responsive.
The screen is 1280x720, which is a surprisingly significant improvement over the 1024x600 of a netbook. Windows simply doesn't work well with netbook resolution, but the Booklet has just enough to avoid windows going over the edges. I noticed the other reviewer rated it down for the screen, as it does have an almost grainy look. After a few days of use you likely won't notice, and the resolution is top notch.
The touch pad is multitouch, and works for three finger back/forth and two finger scrolling. Beyond that it is reliable, albeit small, touch pad. The buttons are a little stiff at first but break in well.
The keyboard is excellent for a device this size, keep in mind it is less than "full" sized. A lot of 11" laptops have come out since that have better sized keyboards since the Booklets release.
Before its release, many people reviewed this device as an "iPad killer". After release it dropped from the radar. I feel that these devices fill different needs. The Booklet is far better if you need Windows applications and flexibility, or need to type a lot. The iPad is a better gaming and multimedia device though. Low power laptops can only play a very limited range of Windows games. You won't get have that concern on an iPad, much like console gaming.
At the time of release, the Booklet filled a very unique niched. On the one side were lower end netbooks, with inferior screens, keyboards, size, battery life and connectivity. On the other side were 13" laptops, usually with even worse battery life but much more power. The Booklet has great construction and features, but is held back by its processor. The only comparable devices were really either far more expensive 13" machines, such as the Adamo or Air and other 11" netbook style devices like the Vaio X, which cost more and had inferior battery life.
Since its release however, this has all changed significantly. Mainly due to one product, the new 11" Macbook Air. This is causing a number of PC manufacturers to come out with 11" devices in response. These devices outshine the "oomph" of the Booklet. A good buy for its time, not as much any more.
