I would say to get Pro before he adds enough features to justify raising the price. As everyone else has said, the interface will be practically indentical, and Moto\Ninja\Philblur is not exactly the grandest UI enhancement out there. I would try the free version for a week, and if you don't like it, don't bother, if you do like it, pay for it and enjoy the extra perks and widgets.
I've bought it. I love it. I'm not going back to blur.
I'll add my +++ to these comments. I have LP+ now, after taking it off once and re-installing it. I don't know if it really makes a difference, but I recommend cleaning off your home screens before you install LP+. It zaps whatever you have and you start all over populating your home screens. However, if you un-install LP+, your original screens reappear, which means they are still there, somewhere in the electronic ether, while LP+ is operating.
I found, on my first install, there were lags and apparent conflicts with certain widgets that I had on the original screen and then again on the LP+ screen. Have had no problems since re-installing over blank screens on the stock UI. Outstanding app!!!
I also recommend the Extended Controls app which enables even further customization of basic operations at a convenient touch. This, LP+ and Vignette are the three best app investments!
Thanks to you all for answering the Froyo question. I, too, was wondering if there would be problems or duplications. Everything is running so smoothly now.
In fact, with Froyo LPP+ gets better, as its contacts widget will work the way it's supposed to, with the pop up window offering you a choice of call, text, email, etc (Motorola saw fit to include implement this feature of the OS this time around I guess).
LauncherProPlus isn't available in the market because the developer lives in a country that Google does not allow to be the source if paid apps. You have to go to http://www.launcherpro.com and pay through paypal.
Just get it. it is now in the Android Market contrary to what others have said. It's three bucks or if you must use the free version. Much better than the stock interface. Much more flexible plus faster and smoother than the stock interface.
+1 more for LPP. You can customize every aspect of your layout. Add Multicon, Folder Organizer and Beautiful widgets and the possibilities are endless. Best $3 I've spend on the market...though easy root is right up there as well.
Download whatever is on the Marketplace (free version) AND the icon pack - very cool stuff. The free app will ask if you want to upgrade to the paid app and take you to the website to do this. All very simple.
Once paid and installed, if you uninstall, you will need to real-download the free version. Then hit menu and input the activation key code (can't think of the actual words they use). Be sure to save activation key code you receive via email at purchase. You will need it any time you re-install.
PS - once you buy from the Marketplace, they keep at record of your apps and will tell you those with updates when you check "my apps". Downloads are as soon as you touch the word, direct to the X. Very slick.
