I would like to be able to get online, Skype, etc. while traveling in Europe. Rather than lug my laptop (which definitely would go against the idea of traveling light!) I'm wondering if a PDA would work. I'm a neophyte to PDA's, but the idea sounds good to me. Has anyone tried this? Is there one you'd recommend? Is there a specific feature I need to look for to make sure it will work outside of the US? I would also prefer not to have to sign up for a plan, but just look for Wifi hotspots wherever I am. Thanks!
