Unfortunately it appears Microsoft has still failed to address the primary issue with the RT: connectivity.
Embedded LTE is not needed. Get a mobile hotspot on your plan. It'd be the same price.
No...the RT needs and has always needed PCoIP support with apps such as VMWare. If they want this to sell, they need to get working with VMWare and get that working.
Until it can securely tap into things as a client, it's certainly not going to sell at that price.
Why would MS want to work with VMware, a company that is declining in market share and is more interested in getting people off their platform?
