Mikesoft started ringing me around 2yrs ago and like a lot of people I thought they were probably cowboys using the fact that we all reacted to 'Microsoft' on the phone. However, once, I actually listened to what they had to say and let them send some quotes to 'keep them quite'
To keep it short, I haven't actually used them for their made up PC's but have purchased Smartboards with installation, digital cameras, video cameras, numerous laptops, network cabling etc etc with no problems whatsoever.
Yes, they can be a bit of a pain with calling but after all it's their business and I find if I say don't ring me for a period of time they stick to it, just spel it out and they respect that.
Prices have always been competitive so our school will continue to use them until proved otherwise.
