It would be very useful. Free WiFi is availalble in lots of places. You may have to ask for the security code in some establishments, and if they are offering a WiFi connection to their customers then they will gladly give you that. Some places don't need the code (sometimes referred to as the WEP code here)
I would bring it, just take care of it and keep an eye on it. They are very popular items here !
Certainly preferable to lugging a laptop around.
I'm sitting in a bar in Athlone checking my mail, downloading Sports Illustrated and sending this post on my Ipad.
We just went with another couple and we both used our iPads every day. The hotels and most of the B & B's have wifi. Lots of the bars and restaurants have it available too. It was very help for directions, restaurants and websites for the attractions.
When I was in the Marble Arch caves, someone on the tour was carting an ipad with them and instantly sharing their photos with the world, thought that was pretty neat :)
I don't have an ipad, but I have a blackberry playbook, which will come with me if I ever get back over again.
Definitely bring your iPad instead of laptop, so much lighter, easier to carry and as Tarry11 posted can take photos and share them instantly! (We found it easier last trip to Ireland in April)
IPad chargers can normally be used with a range of voltages - just check yours has INPUT 100 - 240V written on it - the important bit being 240V. If it has all you need is a plug adapter to the Irish/UK type with 3 square pins.
Thanks to all who responded to my question!! Can't wait for our trip!!!
We are planning on taking an iPad when we go. I recently bought this cool little doo-dad so I can transfer my pics from my camera card directly to the iPad:
