Let me be clear: it is absolutely, unequivocally unacceptable to launch a phone in August of 2012 that runs Android 2.3. I don't care how much it costs. Gingerbread is now three major revisions of Android behind, and there's no easier way to appreciate Android 4.0 than to pick up a MyTouch. Gingerbread is uglier and less cohesive, with little of the design attention the company lavished on Ice Cream Sandwich. It's also considerably less powerful, with stutters and lags that simply aren't present on newer versions of the software. No matter the price tag, I don't know if I can recommend a phone running such outdated software to anyone — even if you're stepping up from a feature phone you're going to quickly grow frustrated with Gingerbread's myriad problems.
Then there's the app issue: a number of Android's best apps and features, from Gmail to Chrome to Google Now, are either entirely absent in Gingerbread or (in Gmail's case) far worse. T-Mobile valiantly tries to replace Google Now with Genius, the voice-controlled app that lets you send texts or do quick searches; the app works reasonably well, but Google's app is better-looking, more powerful, and ultimately more useful.
T-Mobile and Huawei make matters even worse by slathering an eyesore of a UI skin all over Gingerbread. At least Sony has the good sense to add some useful functionality and not overhaul the UI on the Xperia models — the MyTouches could stand to learn a thing or two. Functionally, little is changed, but a lot of menus and icons are customized for the worst. The worst offense is the huge toolbars — in the app drawer, for instance, there's a search bar and sorting tabs on top and a dock on the bottom, so a third of the screen is already taken. The notification pulldown has gigantic power and radio controls, plus a large bar just to remind you that you have a T-Mobile phone — that's a third of your screen that isn't showing, you know, notifications. On a purely aesthetic note, the not-quite-transparent square borders around every icon are absolutely hideous, reminiscent of LG's thankfully now-forsaken skin on the Lucid and others.
There's also a laundry list of bloatware apps preinstalled, furthering the notion that T-Mobile is taking advantage of users who might not know there's a better Android experience out there. There are a dozen or so carrier-branded apps, like T-Mobile Mail and T-Mobile TV, but fortunately if you just train yourself to ignore pink icons (or only use the "Downloads" tab) you won't notice them anymore. Facebook, Slacker, Monopoly (insanely fun on a phone, by the way), Documents to Go, and a few others come installed as well. Some of the apps can be removed, but it's clear that one of the ways T-Mobile offsets the cost of the phone is by filling it with crapware.
