Why I'd vouch for a Treo?

I was using a Treo 650 sometime back and I really liked it.  I'd rate it as the best phone I have used (though I haven't used many smartphones.  I have only used Nokia 7710, Palm Treo 650, BlackBerry Curve 8320, and now an HTC Dream).

I love the way my Android phone tightly integrates with my Google account.  I don't have to worry about backing up my contacts now and then, as they are synced to my Gmail contacts automatically.  The UI (in general, as a computing device, not as a phone) is good.  The device is powerful enough to run all the apps I want to run in parallel.  Lots of applications are available for free download.  The experience I get with this phone is WAY better than any Nokia phone I have ever used.

I still think that my generations-old Treo was a better phone in terms of usability.  Most Palm phones look ugly, I agree; but I don't mind my phone being ugly as long as it does its job really well.  Treo had a very good battery life -- I had to charge it only twice or thrice a week.  The UI was very intuitive and uncluttered.  Everything you need is just there -- ringer volume control and silent mode switch are hardware controls, so you have access to them all the time.  You don't have to switch off the whole device, take the battery out, etc. to change SIM card or memory card.  You can adjust screen brightness with a global shortcut key.  When you are trying to read an SMS under bright sun you can increase the brightness then and there without having to close the SMS application.  There is a universal search provided by the phone that searches the data stored by all applications.  When I search for, say "Siva", it will show me the contacts that have the name (or a note or any contact field) Siva, SMS messages, email messages, notes, documents that has the word "Siva".  It's like Google Desktop for your phone.  (Sadly, such a feature is not in Android phones.)

Maybe the new Palm Pre is going to be a tough competition for iPhones and the Androids.  Or maybe not.

Update: Looks like the next version of Android OS will have a feature to search the content in phone, similar to what the Treo had.  (source: Android Community post)
