Thanks Darklight,
I appreciate your comments. The main reason I am considering either of the above (or better) is for e-mail and SMS communication although as Skype was available on the LG Viewty I thought this may have been a viable option.
I did consider Skype on my laptop but unfortunately, as it is my work one, I do not have Administrator Rights and therefore will not be able to download it. They have a strict policy on software downloads and wouldn't even allow me to install the drivers for my home wireless network.
I don't fancy my chances successfully in asking them for access to Skype.
