I have been using the iPhone and NetSuite together and it does work well. It doesn’t matter what size your dashboard is, it fits perfectly. You can even have multiple windows going at once. On wifi its perfect, without wifi it can be slow. I can do everything, run reports, edit my theme and all. Basically everything you can do on a regular computer. One thing I haven’t figured out yet is copy and paste, simple, but I don’t think it is an option. Usually, I just like to read the user group on my iPhone!
Definitely a convenience. Some companies have even done press releases about NetSuite and the iPhone
