Windows 7 Starter is a basic, more limited edition of Windows, designed for cheaper and/or less powerful computers. It has the following restrictions:
You cannot buy this version of Windows by itself, as it is only available to manufacturers and system builders.
As long as your computer fits the minimum specs of the higher versions of Windows 7, then you should be able to buy, for example, Home Premium and install that.
For more information, refer to the Windows 7 editions article on Wikipedia
Joshhunt said it best about what Windows 7 is (so +1) - it is simply a restricted, cut down version of Windows 7 - take a look at Wikipeda's comparison page.
As for the second part of your question, I like the HP laptop - personally, I wouldn't buy anything Atom right now - the N270, N280 has been out so long that they are due an update very soon - so you can either buy a newer device for the same price, or existing devices will be cheaper. This is a personal choice and you have to ask your self if you are willing to wait for the new or do you just want it!
Yes- You can install regular Windows 7 on the laptop without any problem.
Mind you, the HP mini is not a laptop but a netbook.
a 10" screen and a crammed keyboard is not everyone's cup of tea, they're certainly not ideal for heavy work. they are however great companions.
if you want a netbook, they specifications are pretty much identical, the differences are the display (the HP display is a pretty decent one) and the battery life (4 hrs for the HP mini is a rather mediocre value, some ASUS Eee PC models can easily double that).
