Its been a long road to 4.5 and quite a fun one.  I was lucky enough to  be involved in the beta to this outstanding product and finally as of today I  can talk about it.  To download View 4.5 go to this link:

<!--more--> The first thing most everyone will notice with 4.5 is a completely new  Administrator interface.  This has been much improved from 4.0.  Some of  the best things are being able to sort by all kinds of different  information, in my environment I use the sort by Snapshot all the time  as this allows me to see what Desktops are running on what version of my  snapshots.  (We use multiple snapshots to manage our desktop image, v5  will be the next version that will include the offical 4.5 release  Agent, if that gives us issues we will recompose to v4 which has the RC1  of View 4.5)   My least favorite thing: its still flash based so you  can't access it from an iPhone/iPad.  I'm not an apple nut but I would like  to reset a desktop from my phone, Adobe and Apple just don't get along.

In my implementation of 4.0 I had a lot of issues with composing.  I can  tell you first hand that composing works very well in this latest  version.  I have not done linked clones on Windows 7 yet, I'm still  waiting for Teradici to release their graphics offload card before I go  to 7 on a large scale, however I've pushed it pretty hard on XP and have  found that if I get an error its my fault.  This is a great improvement  from all the weird ssd and other errors I would get on 4.0.

Some other features people will love are:
<blockquote><strong>Offline desktop:</strong> Not something I need here in a  Health Care environment, but something I could see as VERY helpful in  other environments.  As the name implies, this is basically taking a  View Desktop with you, on a plane or whatever, talk about cool and  probably the area that could affect the industry the most.</blockquote>
<blockquote><strong>Kiosk Mode</strong> : This is a must have for the Health Care  environment.  I have a bunch of zero clients booting without any user  intervention, very cool.  It removes the change factor for my deployment  as most of my users just see a new monitor and don't even realize the  change, which is exactly what I want.</blockquote>
<blockquote><strong>Windows 7 Support:</strong> Windows 7 works great virtualized,  I've been running it for six months now, and I'm writting my blog (and  every blog I've written for the past six months) on my virtualized  Windows 7 box running off a Zero Client.  Oh and yes it supports dual  screen without a hickup.</blockquote>
<blockquote><strong>Smart Card support:</strong> It does that too, however don't  get your hopes up for those of you (like me) that are running a zero  client shop.  The only card I know that works with the zero client is  the CAC card (google it).  Although you could probably install the smart  card software within the VM, but that defeats the purpose if you ask  me.  (If someone has experience with this please comment below - also if  you know anything about running a prox card on a zero client).

<strong>Role Based Administration:</strong> This is outstanding for those of us who allow helpdesk to support the  View clients.  Now I can have them access the View Administator and have  limited access to just reset or recompose a desktop.

<strong>Location Based Printing:</strong> Who doesn't love the sound of that?  Make sure to download the View  Administrator Guide and search for &quot;Location-based&quot;, it should be under   Configuring Policies.  This basically uses Microsoft Group Policy to  automatically attach network printers that are near the desktop being  used.  Very cool.</blockquote>
In my opinion your biggest issues will always be USB issues.  This is  the case with all remote access technology.  While XenDesktop and VMWare  View have made leaps with this level of support they still have a lot  of work to do on USB support.   I know there are some big things coming  down the pipe with regard to USB so stay tuned to those.
