I don't know if this is just drive by blog spamming/advertising, or if you actually intend on interacting with potential users here. Since I am feeling nice today, I will assume the later until proven otherwise (ie. what I am about to say is never responded to).
First off, I tried the program. It worked very nice. The animation was smooth and looked sharp. It didn't seem to have any problems with Object Dock Plus running, as some other Expose clones seem to. And even though it was the trial version, I could tell this program looked nice and did its job well to a degree. In fact I was ready to pony up and buy it this very morning. Then I hit the two biggest snags.
1) Price--Now I have no problem paying $20 for a good bit of customization software. I have done it in the past and will do it again in the future I am sure. But the problem I see is that every other Expose clone I have seen for Windows costs half what you are charging. WInPlosion and a couple others I can't recall the names of off the top of my head are all less than $10. I see this as a weakness, since why would I pay $20 for the same thing I can get for $10? I wouldn't. There may be some things that TopDesk does that the others don't, but since the demo was crippled I couldn't tell.
2) A crippled demo--This is a tough one. It is great to not have a timed demo, but to have many of the features missing makes it tough for me to compare to the other programs. WinPlosion has a timed demo (10 days) that is fully functional, so I could see all the settings. Tough call here, because I love that it wasn't timed (or didn't appear to be), but having it be crippled makes it hard to get a feel for the program.
3) Resource use--Perhaps it was my aging system, but just sitting there, on but doing nothing TopDesk was using over 27 megs of RAM. That is quit a bit, again when compared to the competition. Others usually run (on my system at least) in the <10 megs if I recall correctly. Almost 3 times as much RAM use when idle is also a big drawback to regular use for me. I don't mind using programs that take some RAM for the sake of eye candy, but when I can run a complete Desktop X theme with 6-8 objects and use the same or a little less RAM than having TopDesk sitting idle, well, that is another strike against the program.
Again, I thought it was a great program, but had some serious drawbacks that, if addressed in some manner, could really push the potential of the product. I hope to see a response.
