How old IS your computer?
How old ... four years, I think, probably more. It's an IBM PC that was acquired by Lenovo and subsequently given away as a free gift when my family's Internet connection was upgraded.
Maybe, but it does get a bit frustrating and boring after a while. Bejeweled Twist is a bit more accurate, but it doesn't offer Mac support.
I don't think it's fair to make judgements like 'there are no good new games' when it doesn't sound like you've played any.
Have you looked into consoles? Most of the good titles can be found there as well.
I have seen some console gameplay at my local retailers and while I sit on the train. However, I'm still more or less entrenched in the computer era, where the PC and laptop serves as a workplace, playground and media hub all in one. In addition, there are quite a number of older and/or open-source, free games out there that can more or less satisfy the games I want to play without high system requirements (FS2, D3, Tyrian 2000, Raptor and The Battle for Wesnoth, for instance), so I see virtually no need to get a console or play a game that's ultra-realistic but have exorbitant system requirements.
I honestly do not see the point in getting a souped-up PC. What's the point if...
1) I don't have the space in my house to accommodate it; and
2) technology advances so quickly that, whenever you buy something new, it becomes outdated in 24 hours?
I find it pointless and an unnecessary drain on my money. I'd rather play a game that runs smoothly on what I have than own a game that's very pretty but runs so slowly on my computer to the point of it being unplayable.
