For those who have not used a trackball before it will take some getting used to, and the experience can be described as fiddly at best. When using the W500 in the office, we found that plugging in a USB mouse was a necessity.
By comparison, the similarly sized 10.1
Asus Eee Pad Transformer hybrid comes with a full sized trackpad and the ability to fold the screen when the
tablet is connected to the dock.

Considering that the Asus Eee Pad Transformer has dimensions of 271x171x12.98mm, which are very similar to the 275x190x15.95mm of the W500, it does feel that it has been left in the dirt by Asus.
Software
Acer ships the tablet with Windows 7 Home Premium, so it is not optimised for business use. However, it will provide a better desktop-like experience than other tablets.
The internet experience resembles that of laptops and netbooks, with access to all browsers such as IE9, Firefox 4, Chrome and Opera.
Preloaded software comes in the form of Microsoft Office Starter edition and the usual anti-virus software free trial. Another feature is the Acer Ring, an interface created to make use of the touch-screen functionality.
Users are able to browse the internet, and
access applications such as notetaking, camera and the calculator, from the Acer Ring. The My Journal feature is an aggregator that keeps web site updates, and Clear.fi allows users to search, share, and play back music and video over Wi-Fi.
The onscreen keyboard is the same as on all
Windows touch-based devices. It is easy enough to type web addresses, but is not suited to long emails. It is very poor indeed when compared to the virtual keyboards on the iPad and Android tablets.
Battery life fell short of the six hours claimed by Acer and this was disappointing especially when its portability is being touted. The W500 lasted a reasonable two hours and 49 minutes in the the Battery Eater Pro Classic test, which simulates high-intensity activity.
In the Reader test, the device topped out at three hours and 21 minutes. Realistically, the battery will last somewhere between these two figures when the dock is connected.
When we used the W500 in the office as a desktop replacement it managed three hours and 20 minutes with 36 mins of hibernation, backing up the result of the reader test.
In comparison, the Android Honeycomb Asus Eee Pad Transformer offers up to 16 hours of battery life when plugged into the dock, and the forthcoming Motorola Atrix lapdock aims to provide up to eight hours.
The iPad 2, meanwhile, lasted 20 hours during our testing. We clocked nine hours of actual use including browsing the internet over Wi-Fi and 3G, watching three hours of video from BBC iPlayer and a two-hour film. The remaining 11 hours were spent in standby, eight hours of which was overnight.
The design flaws together with a total price of £519 to get the dock could put off some users, however the fact that the tablet runs Windows could make it attractive to businesses.
