I have found that loads of Lotus Notes syncing apps for android are very, very expensive!
I'm testing an app called MyLink that can sync your email, calendar, apps etc… wirelessly and over usb. No need to have your PC left on either via wireless. Looks promising and they say it will cost less than $10 as a one off purchase. There will be a free version too, one to watch for sure! Not sure when its out.
