iPod Touch as a PDA

Yes, it's good for all of those. If you're interested in investing a chunk of change into your iPod as a PDA I would recommend "Things" both the desktop and iPod application.

you can get the apps at CulturedCode.

 

I got my Touch to replace a Palm Tungsten and I haven't looked back since.
I love this device. I tried a couple of free calendar and To Do apps to improve on the calendar included with the Touch. I finally spent the $13 for Pocket Informant which has integrated calendar and To Do list, and I think it's terrific. I've heard some people say that the Touch is not great as a PDA, but I get the feeling that these are people who use a PDA a huge amount for lots of business appointments etc. For my purposes it's perfect, and I also get the benefits of music, podcasts, web browsing and great apps.

 

I bought a 4th gen ipod nano as soon as they came out. I also bought a new touch, justifying it to myself as a 'PDA device'.

It does it very well. The built-in apps are great, you can get more apps and games - many of which are free, and the others are cheap, and you can also listen to your iTunes music and watch your videos on it.

Do it. You'll love it

 

I had an old 2003 HP iPAQ that I replaced in November with a Touch. It does all the things I need from it, except that I used to use a pocket Excel spreadsheet for my checkbook. No spreadsheet edits now, but I got an app for that purpose and it works out fine. I use the calendar all the time. Not sure if you have a Mac or PC, but I love the integration of the Calendar, Mail, Contacts, etc. I sync all my info through those programs. I also love how I can mouse-over a date and time in an e-mail message in Mail and it will give a drop down box that allows me to add it to my calendar. A lot of people feel that Mac's Calendar is under-powered, but it suits my needs just fine.
