PJM  All bow down before the magnanimous ones: mighty Microsoft, generously producing Mac software for 20 years. It wouldn't be that they (perhaps, perhaps?) make a truckload of money out of the Mac BU now, would it?

The day that this ceases to be the case --if it comes-- is the day that they'll shut this part of their operation down. Given the performance of Office 2008, and the lack of Visual Basic for Applications (don't worry, it'll be back for the next major version! Can't tell you when that will be though. Hang in there...) I won't be shedding many tears if that happens.   
(Version 12.2.3)

PJM  Consistency mongers be damned: thanks be to Apple for reverting back to the behaviour that many of us have used since the dawn of time.

HOORAY!   
(Version 9.0.1)

PJM  Wow: who would have thought? 2.2 Beta in August of 2007 (tragically late to the party), and 2.2b11 in August 2009. Let's see: OS X was released in 2001: I've got it... textures is software made by Rip van Winkle.

Seriously though, I have some sympathy for the poor folk who coughed up for this thing in the hope that a decent product would emerge in a finite amount of time. Not looking good... What comes first: the heat death of the universe or Textures for OS X?

PJM  More than 100% CPU usage is not such a tough trick if you have two CPU's... (and, depending on how you calculate even if you just have multiple cores on a single chip).  
(Version 1.73)

PJM  Man, you are seriously *old*: 50 decades of amateur photography? Back in your coffin...  
(Version 1.4.1)

PJM  Wow, thanks for telling us: now I'll have to request a refund. Here I was thinking it was a good purchase backed by a dedicated and responsive developer, but all the while I was obviously deluded. Ah well...  
(Version 2.0.1)

PJM  Hmm, lets not get too carried away with the "everything a Mac app should be" sort of claim. Pull a random task from the sky, something everyone would likely wish to change about Vim's default. Let's say: "change the default font". Everyone knows how to do that: you dial up the preferences for the application, find where the font description lives, change as desired, and away you go. Don't you? Oh... Well, aah, not exactly...

In fact with Vim you really need to learn about initialization files, about how to write a prescription using Vim's style of parameters (is the font option one with an equals sign in it or not?), how to prescribe a given font on a mac in a way that vim understands, etc etc. All of which is achievable, but it's far from being what a Mac user would expect.

Don't get me wrong: I love vim, and use it quite a lot (more from the command line than via MacVim). But I also use TextMate all the time, and there are really good reasons for doing so: it just integrates into Mac OS X a whole heap better than MacVim. Writing your own commands, throwing hooks into the operating system, and so forth is utterly straightforward for anyone with some scripting experience (perl/ruby/python... etc, take your pick).

(Version 27)

PJM  Can you really not guess?

(a) it's not "every few days"

(b) you don't have to update: the world will not explode

(c) plenty of users would prefer to have fixes released promptly

(d) all of the above.

Make your choice...  
(Version 1.64)

PJM  Did you even *look* at the product before your fingers typed this nonsense? Hint for the clueless: read first.

ssh keys work fine with ExpanDrive.  
(Version 1.1)

PJM  Wow, touchy! Really, latex is only hard when you're trying to customise document formats beyond what's supported "out of the box": for simply inserting equations into another application (eg as editable pdf's via linkback and latexit) it's at least as easy as driving the hideous GUI that's part of MathEQ.

Still, if you can't tell the difference between the output from Microsoft Word's Equation Editor (which MathEQ resembles to a frightening degree: maybe they have common parentage?) and an equation typeset in latex then I wish you luck... If you can, and appreciate the extra quality of the output, then the "techy" barrier to using latex will look trivial.
