I don't work in the office (has easily over 200 office staff), but if I did I'd be very frustrated with their slow PC's as my home/gaming PC is just a pure beast in comparison, and its not even a very expensive / suped up gaming PC (worth over £3k brand new?).
Even their monitors, most have single screens, some have 2 screens. I would so have 3 screens. Actually, their monitors are crap anyway, something like 720p or equivalent, most are 4:3
Their internet/LAN is so very slow as well.
Just terrible for a multi million pound company.
