I don't really know what shared hosting solution to choose from neowebspace.com. Linux or Windows? What is the main difference?
By the way, do you know any discounts on their shared hosting plans?
I can agree with Shakir and you like to say that over 95% of applications can be run on Linux platfrom, 100% of applications can be run on Windows, but it is a bit expensive. As for Neowebspace.com, think that you can trust this company because it is well-known and has been providing qualitative services for a long period of time.
What are you going to host via this company?
I can share a discount: SPACE which will give you the ability to save 20% off the price on their shared hosting deals.
It happened so that neowebspace.com can be good if you are looking for reliable web hosting services. Their web site is convenient and you will be able to find any information you need to know about this company and its offer.
You'd better contact their support and ask them about the solution you need.
Linux and Windows support different applications and if you want to use a specific application, you much check its compatibility with the Operating system. If you have a website built in asp, asp.net or MS-SQL or you are willing to use any Microsoft application like ColdFusion or any other, you will have to opt for a Windows based hosting plan. If not, than you can opt for a Linux based hosting plan
