I like that this was something new for us to have as opposed from using our normal computer repair shop which has been doing it since we started (and they're great!).
Also their customer support staff are wonderful! The only thing about them i didn't really care much too but if you don’t mind then maybe try not having all your computers in one place at once? We had laptops with different companies/employers so when someone came by my desk or mine went out - there wasn'y always another person who could help me get back up online quickly enough without going into work early just because theirs down also etc... This solved some problems!!
