The ICONIA TAB W500 & W501 could prove to be worthy competitors to the Asus EEE Pad Transformer and the Lenovo Ideapad U1 Hybrid, both being tablets that can transform into netbooks.
The Acer models though come with a few tricks of their own; firstly you can choose between the non 3G and a 3G version for £450 or £530 respectively with the additional keyboard costing £50 extra only.
Then there's the platform; Acer used the AMD-C50 dual core which is a good compromise between a low-power Atom processor and a fully-fledged, desktop-class Core i5 as used in the Asus EEE Slate EP121; it is a dual core model clocked at 1GHz with integrated AMD Radeon HD6250
There's also the sheer amount of features; the W501 weighs 1Kg, has a 10.1-inch 1280x800 pixels LED-backlit LCD screen with 2GB RAM, a 32GB SSD with an additional optional 32GB microSD card, a 3260mAh Li-polymer battery pack that promises up to four hours HD video playback and six hours internet browsing, two 1.3-megapixel webcam with HD recording capabilities, Wi-Fi, Bluetooth, 3G, a HDMI port and Windows 7 Home Premium.
As for the keyboard, it is a full size chiclet model with an Ethernet and USB ports, a pointing device with two buttons for navigation but unfortunately no built in batteries it seems and adds roughly 300g to the 720g that the tablet weighs on its own.
