Dell Latitude 10:
My "secret" favorite.
Pros:
a.) User-exchangeable battery. There even are 2 batteries available, the huge one sticking ca. 7mm out of the housing. I love this. Sometimes, when traveling, I simply don't find any outlets to charge. The price of € 60 for the additional battery is okay, I've seen much worse.
b.) Rubberised and "streamlined" back panel. Very convenient to hold. There are some indentations (right and left, when holding in landscape format), extremely well designed.
c.) Due to the Atom processor no fan, no heat. Main reason why I bought it.
Cons:
a.) Physical home button. I'd rather have a capacitive one.
b.) No keyboard solution. A bit unfair, I admit. For now, Microsoft basically is the only one with a solution. But Asus, for example, at least offers their own cover with an integrated Bluetooth keyboard. For Dell, I only find the usual solutions: 3rd party leather cover or standalone Bluetooth keyboard.
c.) No place to store the WACOM pen. Surface Pro allows for magnetic connection to the power connector.

Microsoft Surface RT:
Pros:
a.) Touch and type covers are a stroke of genius.
b.) Relatively light and good battery life.
c.) Unique "industrial" design, very "valuable".
Cons:
a.) Still rather limited app supply.
b.) Still some confusion amongst customers re. legacy apps.

Microsoft Surface Pro:
Pros:
a.) Touch and type covers are a stroke of genius.
b.) Windows 8 Pro "Powerhouse".
c.) Great display.
Cons:
a.) Not-so-great battery life = ca. 4 hours.
b.) Rather heavy for a tablet.
c.) Fan not too disturbing, but getting a bit warm on the other hand.
