The old IBM building was at Turtle Creek and Gillespie Street. If you are wondering about online shopping....NO problem. But now I see you may be talking about opening an online store....No problem there either. There are several browsers you can use, I normally use Firefox and I have Opera. I have to use Opera when I go to Ancestry.com, they may now support Firefox but a few years they didn't but that is no big deal. You will get software updates as needed that you can install when convenient and they are free. Some require a reboot but most do not. And you can leave your computer running for ever and never have to reboot because of memory leaks like with microsoft. Those memory leaks may be what's slowing you down now....but they will deny they exist. Back in the 90s I had a girlfriend who had worked for AT&T during the lawsuit era, when she found out that we had worked for Carterfone she wasn't very pleased with me.
