The one great thing about Android is that it's open enough to let you choose.
Don't like the keyboard? Download another one. Don't like the look - get a new theme.
Don't like the email client? Download another one.
Don't like the browser? Download another one.
Don't like the calendar? Download another one.
Don't like the quality of the text-to-speech? Download another TTS engine (e.g. SVOX).
And so on.
That's all before you look at all the widgets you can get to convey information in a range of ways and styles. Many are free, and most are as affordable as anything from the Apple App Store. You even get to try the app out for 15 minutes to check it works, or else get a full refund.
You can even get replacement camera apps, although so far I've not found a way to get handsets with dedicated camera keys to load a different app.
Agree, this is the great thing about the mobile device world we live in/are about to live in. It is true for other devices as well, but is really the easiest and most advanced with Android. I had a general social commentary to this effect typed up in my response to Nazzy, but I didn't want him/her to feel like I was lecturing at them, so I'll throw it here as it is the same line of thought:

Here is my perspective on this, beginning with the iPhone and continuing with Android and will extend to all "smart" mobile devices- Gone are the days when the manufacturers have to do anything beyond putting out competitive hardware, working firm/software, and flashy marketing. Think about PC's/Mac's, you buy a computer, and it has some stuff pre-loaded, but that pre-loaded stuff might not (probably won't, actually) do what you want and need it to do; so you turn to the online and brick-and-mortar ecosystem for finding the software (and hardware- think specialty keyboards and mice, etc.) to accomplish your ends. For a long time phones/PDAs/Mobile Devices had a lack of uniformity and so a lack of a reliable ecosystem for doing the same- if a device didn't do what you needed out of the box, you returned it for one that did, didn't buy it, or jumped through hoops (or learned to develop) to make/get what you wanted out of it (Windows mobile and Palm might be exceptions to this, but you had to actively seek the enhancements). And so we had these expectations for mobile devices, separate from our conditioned expectations of computers, to be fully-functional right away. Does anyone remember how miserable the first iPhone was until the app store launched? How about the early days of the G1, before the Android Market had more than ~50 apps? This actually pre-dates Android and iOS both (for some of my fellow math class nerds- Texas Instruments really started this in the late nineties; you could use their calculators as they were, do most of your math long-hand, and use some of their specialty programs they wrote, or they encouraged people to write their own programs and share them on forums on the internet. Windows mobile and Palm also did similarly (but they weren't really sponsored by/encouraged by the manufacturers and they still continued to try to include everything they thought you needed). In this case, HTC was developed a keyboard that they think is what people want and need, and for most people that works; but HTC can also quickly scan the market and see literally at least a thousand of keyboard apps and themes available, many for free, so why be inefficient and waste resources duplicating what is already available? And I don't really see this evolution as a bad thing; personally, I want HTC to spend resources on streamlining Sense, and developing drivers and firmware for the latest and greatest hardware, as I personally use Swiftkey or Swype, or even voice-to-text instead of the stock keyboards from any manufacturer.
Phones and tablets really are slowly replacing PC's/Mac's both in terms of functionality and marketing ecosystem. But we are still right on the cusp of this paradigm shift, and still have a lot of users with the "this works fine" non-innovative settling mentality (and Apple has really kind of hurt the transition to this user-customized world), bucking against the manufacturers trying to keep costs/prices down. This will normalize before too long, just like the PC market (remember when MS Office became the standard for everything, yet wasn't included in the price you paid for PC's), when we as consumers condition ourselves to find and apply what we want (like we do now with cars and computers and houses, etc.), not simply buy it and discard it.
