I just spent a week at the AAJ [American Association for Justice] convention in Chicago, soaking up knowledge and becoming chair of the Employment Rights Section for this coming year. I took with me my new iPhone and the following are my findings, so far [some of many]:
To keep the battery as full as possible, I have Bluetooth off and Searching for Networks off and had the phone fully charged early yesterday. I used it a fair amount [mainly for phone calls] yesterday. I did watch YouTube's The Ultimate Canon [Pachibel's Canon played by rock guitar - very neat] for about 6 min. I just checked and the battery bar is almost full [prob. 90%].
It works great - I have it set up to cc to me [so my GMail account has my sent messages in it too] and I don't sense email is not getting through. I have email transferred/forwarded from my HL account [a GoDaddy email acct.] to my GMail acct. from whence I get it via my iPhone. I have had iPhone set on getting mail every now and then but switched it back to Manual so it wouldn't be doing it all the time. If I have my laptop, as I do now, I go into GMail and delete or archive out of the inbox all the emails that have gathered there [such as those for yesterday] so they won't be picked up by the iPhone, as I don't need to read them on the phone. However, they are in the archive area if needed. And they've been downloaded to the laptop, as I check my mail. David Pogue recently wrote about this in his blog.
As for finger size, that could be a problem though the letters get a bit larger when you're on top of them so you know what you're punching. The auto complete feature is great - instead of punching the last letter I can just hit space, which certainly is big enough. So you have 4-5 or so regular letter punches and the big space punch. Another thing is that one's fingers have edges on them. I find that if I use my right pointer finger just slightly turned that works best - it's just more of an edge there. Fat fingers may or may not have a similar high point or edge which can be used. I do know that pressure doesn't help and a light touch is all that is needed.
All in all it was a wonderful experience, going to a convention without hauling around my laptop and instead, using my iPhone to gather emails and check the web.
