I'm not sure how this will change small businesses' computing habits in the short-term but if service providers do take advantage of such services, it can go a long way in allow mobile warriors to gain access to certain data and the only thing they would need is wireless access.
I can already see a lot of advantage in just such a system. I know that this is a business oriented service but I can also see companies offer more consumer services as well. If consumer cloud services doesn't come from VMWare's partners, I do see traditional companies offer them in the next year.
It's been a while since we've talked about cloud services as most are still geared towards big businesses. But watch out. 2009 could be a cloudy year.
