Hi Mike,
First off I'd like to thank you for Pleco Dict, it has been such a great help to me, I'm not sure how I would have gotten by in some of my travels without it.
Secondly, I'd like to put another vote in for an Android port of Pleco, for a couple reasons. Firstly, as linux user I am in a situation in which Windows Mobile and iPhone will not play nicely with my computer. Android, on the other hand, reportedly works well out of the box. I know that linux users are probably a very small portion of your client base, but for the few of us out there being able to put Pleco on a platform that will also play well with our computers would be a massive plus. This, after all, is the whole point of a smartphone.
The second concern I have with an iPhone version of Pleco is that, as far as I know, all iPhones sold in the USA are locked to a specific carrier. This means that if I take my iPhone to China hoping to use Pleco, I will also have to have a second unlocked phone to use with a local sim card. This is a bit inconvenient. Unlocked Android world phones are already available (have you seen the HTC Hero, oh man that thing looks SWEET), and more are clearly on the way.
My old Treo 650 has always been easy to use with linux, and works great as an unlocked world phone, but it's on its last legs and will need replacement soon. The first thing I did before even starting shopping around was to come here and see what the next development of Pleco will be. I'd really like to avoid Windows Mobile and iPhone if at all possible. The old Palm OS was so great because it was so open, easy to develop for, and easy to use on a multitude of platforms. Android seems like it will match this same description, and will be even more flexible I think because it is already showing up on the devices of more and more manufacturers.
Anyways, this is my on my knees plea for Android Pleco. Keep up the good work!
