An an old IBMer, the solution used there was that each machine version (I don't know how many versions of the ThinkPad were supported, but it was more than 5-6, and we were usually on at least two versions of Windows.) had an image, so when you had any problems with the ThinkPad, IT would test it quickly, back up your data files if needed and re-image the machine with the standard image, then restore your data files. Email and calendaring was Lotus Notes, plus the standard MS Office suite of Word, Excel, PP, but not Outlook. So what I suspect will happen is that they will get a few standard MBPs, image them to some standard suite and do the same thing. It's not really that hard to support, given that the solution to 99% of the problems was simple brute force. If the re-image didn't fix it, you got a replacement ThinkPad (not new, just a replacement). As for networking, any WiFi or network connection would work as they used VPN from anywhere outside the company network. The only challenge was that software updates were only pushed when connected to the company network directly, not through the VPN, so if you didn't come to the mothership very often, the pushes got behind and that first connect when you did check is took a long time! I used to make it a practice to visit an IBM office at least every two weeks, just for the pushes. Road warriors learn to cope...
