The Comet is probably what a lot of people are looking for.

Most "smart phones" I have previously tried had annoyed me by being either a little too cheesy or way too expensive. There are a lot of impressive touchscreen phones which always made me think, "that thing could be WAY cheaper if only they toned down the features somewhat." There are also some super-cheap touchscreen phones which made me think, "this phone could be a lot better with only some minor improvements".

The Comet seems to be in the lonely area right in the middle, where the the quality is just barely good enough to handle the most work likely to be thrown at it by most people. And for that, the price is well below all of those "Cadillac-of-phones" phones.

The Comet's acceptable features:

It's not a very high resolution (240x320), but the pixel size is larger than average. So it isn't as large and sharp as better phones, but you still get a good deal more physical space than "normal" phones.

Touchscreen interface:
It uses the "capacitative" type, which means it is a completely solid surface which (somehow) knows when fingers are physically touching it. It does not use the cheaper "resistive" type, which have a flexible surface which must be pressed down to work. It isn't quite as perfectly sensitive as an iPhone, but much more reliable than resistive screens which have different levels of resistance in different locations.

Keypad/text entry:
The medium screen size might be a little annoying for tapping, but this phone uses "Swype" typing. Plunk your finger on the first letter, then drag your finger all over the keyboard to each letter you want, and the magic Swype system figures out which word you want to spell.

EDITED ON 2/15/2012

Since my original review I have received a couple of comments informing me that T-Mobile has dropped their web daypass option. Furthermore over the past year there has been an explosion of cheap android phones released to be used on cheap pre-paid plans. Given these two changes to the market since my original review, I no longer feel that the T-Mobile Comet represents the best value in this segment and have lowered my rating to a merely "average" 3 stars.


Between home and the office, I spend a lot of time within reach of a land line and a computer with internet access. So as much as I may have wanted a smart phone previously, I just haven't been able to justify spending upwards of $80 a month for one. I've been waiting a long time for a carrier to offer a smart phone with a pay-as-you-go pricing model - and after about two weeks of use I can say that I am very happy with the T-Mobile Comet.

I've been using T-Mobile's 10 cents per minute pre-paid plan for several years - previously with a cheap, extremely basic Samsung t209 phone. While I wouldn't really call T-Mobile's call quality or coverage "great", I would definitely say that it has been "good enough" for me while living around Boston and San Francisco, and the price has certainly been reasonable. Historically I have spent about $10 to $12 per month on average on my cell phone bill. I also have family members on the same plan who spend even less.

A lot of reviews that compare the Comet to iPhones or other Android phones that can be purchased for $100 to $200 dollars (or even for free) along with an expensive post-paid plan and a two year commitment really seem to miss the point.

I've been a T-Mobile customer for several years now. They have the best prepaid (pay as you go) plan in my opinion. The minutes do not expire for a year, and T-Mobile notifies you via text message a few days before expiring, so you can add time and roll over your prepaid minutes. Take that AT&T! I typically use about a 1000 minutes per year ($100.00).

I previously had a RAZR phone (which I loved), but wanted a device with more features. My favorite thing about the RAZR was that it's size and weight were very comfortable in my pocket (a guy thing). This phone is just a tiny bit larger and heavier than a RAZR, but it's not noticable. I can walk around with this phone in my pocket all day and not even notice it. I just removed the SIM card from my RAZR, and inserted it into this phone. Your phone number, prepaid minutes, and account don't change.

Now to the phone. I've had this phone for about 6 weeks and I'm very happy with it. Like I said, I keep it in my pocket, but this phone has a glass screen so your keys etc won't scratch it. No screen protector is needed. Also, the fit/finish on the phone is very good. The battery door shuts tight (no rattles), the buttons seem firm, and the connectors (micro usb and headphones) are tight and connect well. My only complaint would be the placement of the volume buttons. When I first got the phone, I tended to press them whenever I held the phone, but this is something I'm getting used to.

The call quality is great, and the speakerphone is easy to use. The phone also supports an in call dialer so you can enter PINs etc during a call.

The main reason I got this phone was to replace my MP3 player. The phone OS (Android) has a built in music player and FM radio. Both work very well.
