The iPad is the most minimalist computer to get by and is still fun to use.
I use now an iPad 2 since a couple weeks and it really is ideal for everything I do online, but doing my job. If I could retire today, the iPad would be the only computer I need. It works great for browsing the web, reading and writing emails, manage appointments, watching movies, playing games and managing photos. It is though to minimalist for actual online work. When writing an article I need to research several sites, have multiple windows open on the same screen, edit photos and so on. A 27-inch iMac with expose filled with open browser windows that each have about 10 tabs open is what is necessary for me to get through a busy work day.
I think the tremendous success Apple has with the iPad comes from the fact that the iPad is simplest and smallest computer that does everything most of us want to accomplish. If you need a computer for work, the iPad will likely, if at all, just a be a companion to your PC or Mac. Did you ditch your Desktop computer and just use the iPad? If yes, please post in the comments below.
I hope until I retire Apple will have solved the issue that I still need a PC to maintenance the iPad. The rumored cloud services could be the key to that PC less future.
