Cisco ISE - General Info. & capabilities

Question

Hello All,
I've read quiet a bit of ISE features, but would like to know the following:
1. Can ISE provide/track details of user activity, like which servers/websites he accessed over a period of time?
2. Can it provide details of how much data was transferred from a particular server to a specific client?
3. For a 1500 user env. (1000 desktops and 500 wireless devices) which model of ISE would be appropriate?
4. How would having ISE be different from already deployed authentication services like Active Directory or built-in application authentication for solutions like Oracle ERP systems?
5. I see ISE as being marketed primarily for wireles devices (BYOD), but how would it help for wired devices (or does it become and unecessary authentication level apart from AD, switch based 802.1x, etc)
Thank you.
Regards,
Adnan

Cisco ISE is a consolidated policy-based access control system that  incorporates a superset of features available in existing Cisco policy  platforms. Cisco ISE performs the following functions:
•Combines authentication, authorization, accounting (AAA), posture, and profiler into one appliance
•Provides for comprehensive guest access management for the Cisco ISE administrator, sanctioned sponsor administrators, or both
•Enforces  endpoint compliance by providing comprehensive client provisioning  measures and assessing device posture for all endpoints that access the  network, including 802.1X environments
•Provides support for discovery, profiling, policy-based placement, and monitoring of endpoint devices on the network
•Enables consistent policy in centralized and distributed deployments that allows services to be delivered where they are needed
•Employs  advanced enforcement capabilities including security group access (SGA)  through the use of security group tags (SGTs) and security group access  control lists (SGACLs)
•Supports scalability to support a number of deployment scenarios from small office to large enterprise environments
The following key functions of Cisco ISE enable you to manage your entire access network.
Provide Identity-Based Network Access
The Cisco ISE solution provides context-aware identity management in the following areas:
•Cisco ISE determines whether users are accessing the network on an authorized, policy-compliant device.
•Cisco ISE establishes user identity, location, and access history, which can be used for compliance and reporting.
•Cisco  ISE assigns services based on the assigned user role, group, and  associated policy (job role, location, device type, and so on).
•Cisco  ISE grants authenticated users with access to specific segments of the  network, or specific applications and services, or both, based on  authentication results.
ISE 3315 can support 1500 users with appropriate license.
