On the hardware side, i haven't seen anything that is even close to the iPad. Just the right size for chart display, clear display and dead simple to use. Some have reported theirs overheating, but I suspect they were left sitting in direct sunlight for an extended period of time or were kept inside a case so they couldn't cool off. I've never had a problem, and that includes while flying in and out of airports with an ambient temperature in the 100s. Glare on the screen can be annoying, I've resolved that with a stick on glare shield that also protects the glass. Tipping the device an inch one way or the other also works!
There's a lot of discussion about how to mount the iPad. I carry mine on a lap board, some folks use yoke mounts, some just balance the iPad on their lap. Whatever works for you.
On the software side, there are multiple vendors who are competing hard for the market with frequent updates and improvements. ForeFlight is a very complete package, geo-referenced charts for the entire US is $150 per year. It's a very polished, very feature rich set up. Also handles flight planning chores, including the AFD, checking weather and filing. X-plane offers similar utility. Flight Guide and SkyCharts offer charts without all of the other features, good options if charts are all you want. All the above use government (NOS, NACO, whatever they are calling themselves this week) charts.
Jepp has their own app, JeppFD. If you have an electronic Jepp subscription the app is free, but that electronic Jepp subscription will be more expensive than the government charts, just like paper Jepps are more expensive than paper government charts. Jepp's package is pretty much exactly what you would get in a paper Jepp subscription. Enroute charts, approach charts and their airway manuals. They are different in that with the government providers you are downloading basically PDF versions of the charts that you can zoom in or out of. With the Jepps you download the raw data and the app puts it into chart format. This makes for faster downloads and allows "track up" on the enroute charts versus North up on ForeFlight for example. Jepp promises geo-referenced approach plates and flight planning funtions "soon", but they aren't their yet.
ForeFlight and Xplane offer in flight weather using ADS-B. You have to buy about $1,500 worth of hardware to get that to work, you must be in range of an ADS-B ground station and the information isn't as complete as with XM weather. Jepp has no weather (yet).
I'm happy with ForeFlight running on my iPad using my 396 for XM weather and letting my GNS 480 guide the airplane. I do have the Jepp app as well, and I find myself using their enroute charts, just because I like the "track up" view. For approaches I use ForeFlight to get geo referencing. I didn't think that would be a big deal, but once I tried it I really like it. I don't use it for guidance, that's what the panel mount stuff is for. But for anticipating what is coming next while ATC is vectoring you for an approach, the "little blue (or yellow, depending on the app) airplane" on the approach plate is great.
As I mentioned above, the vendors are working hard to one up each other with new features, so anything anyone says today may be outdated tomorrow. I should also note that the Feds have indicated that they are going to start charging for electronic charts (they have been free) so costs may go up with the government chart providers.
