I use my smartphone as a super-PDA. I have had PDAs for 15 or more years (Palm Pilots of various flavors followed by an Nokia n800). The Nokia n800 was great having a full linux computer in my pocket, but was bulky. I now carry a Nexus One (going on three years) and it is nearly perfect: * Excellent size and weight (similar to the Palm Pilot Vx, which was my previous ideal form factor) * Super PDA that also has good data connectivity over the cell network (T-Mobile sucks outside of major cities). * Excellent functionality: nice color display for its size. Between Google Docs (problematic if no data coverage) and Dropbox (works great detached for the internet), I can organize my life via text files in Dropbox or spreadsheets in GDocs as well as the calendar app for reminders. * Being able to access the internet for Google and Wikipedia for general information and RSS feeds (and Google News) for keeping up with news is tremendously useful. * Can even be used as a phone! ;-) The only part I miss with my Nexus One is that Android mostly buries linux, especially with it missing X11, a terminal window, and Bluetooth HID (the n800 had X11 quirks, but it was there as well as xterm, and BT HID for a real keyboard).
