1. SEN didn't have a data play and used to partner with a number of data vendors. Now they have had a tier 3 data player thrust on them, previously Enterasys, previously Cabletron. If you are looking for a data solution, Nortel Business Optimized Networking is a lower risk approach delivering 7x the reliability, 20x the performance, requiring 40% less energy and delivering up to 50% lower TCO compared to Cisco.
2. Are you a Microsoft shop? SEN used to be very closely aligned with Microsoft but that relationship has gone belly up. So how will Gores-SEN meet your UC needs? Don't go there. Better consider the Nortel-Microsoft Innovative Communications Alliance with 800 wins to date.
3. Are you an IBM shop? SEN OEM'd voice technology to IBM, so no reason to consider Gores-SEN as well? I would say forget it. The Nortel BM Alliance includes joint marketing and selling, UC software solutions for SMBs (SCS500), joint UC solutions, SOA for Communications Enabled Applications, and joint professional services.
Finally, you should additionally be concerned on how Gores is going to satisfy its investment targets. Are cost cutting and staff reductions planned?
