Question: what android system is this phone 2.0 or 4.0
Document: For the size and price, this phone can't be beat! Very easy to use OS and the Apps available are more that enough for my needs. WebOS may be a discontinued operating system but it is still better than Android and Apple's iOS at multitasking. Touchstone charging is an added bonus!
If you can afford even a used iPhone, Android, or Windows phone, go buy one of those instead. If you're poor or just want something to play with, go for a Pre 2. I would not buy a Pixi or Pre Plus if I were you. These days, the Pre 2 or Pre 3 (which is much more expensive) are the only viable Palm devices to use. The others are just too slow.
I cannot stress this enough, this is one of the best phones I have ever owned! the outside feels reliable and well built with a smooth slider that works perfectly. the keys are not too clicky, but not bothersome either. the main bonus of this whole thing is WebOS 2.1, which is the best OS out there! The multitasking and speed are exponentially high quality, kicking Ios and Android while there down. what this phone lacks in apps makes up in productivity and the community.
It is too bad that support for WebOS is waning. Now that the TNT1200 plan includes 500mb of data I know that I will never go over my limit. At less than $30 per month for a no contract plan I am very satisfied. Verizon does have the best network coverage so I get service everywhere. By the way, I returned an Iphone 4 after 2 weeks of use before I got my first Pixi. Love WebOs despite the limited number of apps.Very, very satisfied.
my new palm pre 2 has met all expectations, battery lasts a full day, like os better then windows 6.5 and android. Call quality and reception are acceptable. query keyboard works for me and I don't have little hands. Wifi works as expected, overall a decent alternative to the other phones, updated to HP 2.1. Thank You Palm and HP.
Good phone and easy to use. Operating system is not common and your work place may not accept/ or have a protocol for it.
At first they said that the new phone was previously registered under someone else and wanted to charge me. Finally I got them to understand that it was new, but they still wouldn't help because, all of a sudden, they couldn't update their warranty system. And without their system saying it was in warranty they couldn't do anything.The OS is great. The device is a perfect fit for me. But if it doesn't work right and there is no support it is just a paperweight. Don't waste your time.
The phone was very hot when first used and battery drained quickly. I found a few users complained about this same issue. For me, after the operating system get update to newer version then the phone worked fine, it is not hot like before. However, the battery come with the phone only last for about four hours on every charge. I replace it with new battery that I purchase separately and the phone works fine now. The key pad is not easy to type  even my finger is small.
This phone is smart. Super smart. It can keep up with you no matter how fast you are opening and closing apps, or moving from Facebook to messaging. That said, I have had this phone for almost two months and it is already having a few issues. At times it won't receive messages. I reset my phone one night and I received 20 messages at one time from as far back as 3 to 4 days prior!!!
I'm not joking when I'm saying it burned my hand. I'm wondering, now that the phone is packed and ready to go back, if my unit was defective. Because if a lot of people experienced this, they're either ignoring it or they don't know how unusual it is for a phone to get that hot.-My Yahoo! mail wouldn't sync. I kept getting an error. I deleted the account and set it back up 4 times.-The battery life is terrible.
