Great blog wponder. Thanks for the video, I have to say that's impressive on a zero client. I loved the dual screen as well, seems to work flawless without those common errors like the taskbar spanning two screens. Anyway thanks man, can't wait to test this on the V10L, maybe I'll shoot a video next time to compare the two.

This is just my personal opinion:
I think your concerns or questions are natural. In the end, it all comes down to what matters and works best for you. We are all about choice and options. Some people look at their clients as disposable some people look at their clients as strategic ( Giving them the most flexibility and feeling of comfort )
There is inherent value in a multi-protocol client. It gives you the most broad flexibility and I do not think anyone would argue against that. Although, a PCoIP zero client also supports RDP it's not entirely equal comparing to a multi-protocol client.
>> Does it worry you that the P20 only supports PCoIP?
Technically, it also supports RDP. So, It does not worry me that it's built for PCoIP. I actaully, have never been afraid of purpose built clients. When managed desktops we had a 5 and 10 year roadmap and we were set usually set on a direction for at least 5. For some, this really is not an issue to them. They have made an architecture decision and that is the path they are headed. I also think depending on how you depreciate your clients and how you look at your architecture 3 years / 5 years etc. that factors into how a big a deal this really is.
>> What if VMware
abandons PCoIP,
There is no guarantee here or is there with anything though? Only you can look the level of investment and commitment and decide. That is true of anything. That said, there are standard support statements, product life cycle terms etc. A company like VMware is not going to ship something, just drop it and walk away leaving you hanginig. Companies, EOL hardware and software or change things all the time. That is a risk with anything unless you build it in house. Then it's just a question of when the next Executive comes in and decides it's cheaper to do it differenty On thing is certain, change, it's always going to happen.
>> or some new version of PCoIP isn't supported on the P20.
This is not specific to just a P20. This applies to ALL thin clients what is supported on one might not be supported on others. After all, that is why there are so many models right? Some are fit for basic connectivity, some fit for connectivity + other tasks. I think you need to look out into the future and say, in five years will I just need basic connectivity or, will I want to do more multimedia, VoIP, Webcams, USB, 3D graphics, more rich desktop experiance, multi-monitor etc.. Clients today often do not support features of tomorrow even if they do support multiple protocols. Then pick the best client for your roadmap.
The probability of this is really low with a P20. The current generation Tera 1100 started out on the highend and is now working its way down and Teradici is still adding features to it though firmware updates. There is the chance new features could require updated clients in the future, that is common. However, making it so that an older client could not connect to a newer backend minus the new features would be CRAZY. In fact it would be suicide ( IMO ). So, I do not think this is likely. Look at solutions like Sun Ray. Sun Rays have been shipping for over 10 years and have only had 2 generations 3 clients in each generation. Sun Ray 1 / Sun Ray 2. The Sun Ray 1 can still be used with existing SRSS solutions today minus only a few newer features.
>> The P20 just worries me because it's not flexible. I know I'm not the only one with these thoughts.
It's a Coke and Pepsi world. For some there will be concerns and for others there will not be, and this is exactly why there is choice!!!!! I have some visibility into what people buy and the decisions they make. There is no question, people are buying PCoIP clients without concern. There are also lots of people using existing clients. If a P20 is your thing the best thing about is you have the backing and support of VMware, Teradici and WYSE. If another WYSE model is your thing, the part about that is you have the backing and support of VMware, Teradici and WYSE.
wponder, I appreciate your thorough response. For one it's nice to know the R20 supports RDP, at least that gives us terminal services as a backup plan. Again I appreciate your video and thoughts throughout this thread. Like you said there is no single answer, but I think this forum is a great tool to discuss these concerns. I'm still not 100% sold on the P20, but as the V10L PCoIP support is a ways out and Wyse isn't giving me answers on the next WTOS PCoIP release, I think P20 is probably the way to go... unless something better comes out tomorrow.
