The originating group of developers are actually rather brilliant and came up with one of the fastest p2p communication protocols. Once the closed-source version of Skype opened up, it went a tad downhill with every kid releasing their own client. I don't recall specifically whether or not the n810 client is put out by Skype themselves or not. All I know is the official Skype client runs like a champ on most desktops/laptops without issue.

I don't think grouping Skype as terrible/sucky is the way of going about it either -- since by doing so you're now discounting every client released as well as the API (which is all Skype is anymore). Could it stand improvement? Yes. However, it works for me and I haven't had an issue with it.

It's the same thing as saying "AIM sucks" -- the client, the Pidgin plugin, or the protocol?

As far as the n810 is concerned, it looks more like a glitch from Nokia's end on this one. Especially by not flashing all new devices with the latest firmware. Flash the device and it'll install, cause that's how I went about getting it installed.
