You need a new PC, but looking for compact. I already have my eye on a
Xi3 but that is just me. I will eventually get one, and I will be one happy camper. I like the fact it is easy to upgrade compared to laptops and most desktops.
The one drawback I see with you wanting something like this is that one would need a separate monitor, keyboard, and mouse. Other than that, I really do not see the reason to get a laptop. Yes, they are very mobile, but the upgrading of one in the future is not always easy. If you only plan on having the PC for five to ten years, then maybe a laptop is the way to go for you.
No matter, choose what you want, and hope that you purchase something that can complete the tasks that you throw at it. Any Walmart PC can create word documents and be able to handle other office tasks. However I would not recommend purchasing a Walmart PC for playing the latest Crysis or other high cpu and gpu extensive games.
Good luck with your choices...
