Yes.
You should still play Portal 1 at some point, it's just as good and there are some mechanics in the game that aren't present in Portal 2. Plus, it's more challenging (IMO, your mileage may vary.)
I posted this answer somewhere but can't find it, so I'll repeat myself here. I briefly played the orig Portal when it came bundled with one of the Half Life 2 Episodes. I only got through a few rooms and said "boring". And compared to HL2 it was. But now with all the P2 hype, I decided to go back and finish it. It turned out to be a good puzzler, with humor and threat and the end of the "testing" process was brilliant and hilarious (at least to me). I love the voice and it's comments. Most important is that in the past with most games with built in puzzles, I either don't have the intelligence or the patience to figure out puzzles based on odd obscure relationships. In contrast in this game, every setup seemed to be logical and straight forward as long as the physics does not blow your mind and under the circumstances, my analytical thinking was able to prevail.

I impressed myself by being able to complete Portal (original) without referring to one online cheat/walk through. In some cases the answer can be illusive, but eventually will be found. Jumping/flying solutions were the most dynamic and fun especially when you have to

If you have not played it, here is one easy cheat/example, so easy I spent 30 min trying to figure it out:
spoiler> There is a duct you climb into with a spinning fan, that you can stand on, the only way is down, but when you point your portal gun through the fan it does not show as able to project a portal to the other side. However if you stand back from the fan and look through it at an angle you can shoot a portal though it. Shooting energy orbs through portals to solve puzzles becomes very prevalent later in the game. <end spoiler.
My wife likes puzzle games, but not ones that require physicality, moving/fast reactions, therefore she would not like this game.
Question: I noticed when playing this game (original Portal) on my MBP that every 5 or so minutes the game would freeze for about 20 sec and then resume. Is this a known issue?
I think I'm going to wait for half-life epsiode 3 and some sort of portal2 bundle.
plus I'll be too busy to play it now any ways

That's how I got it the first time and this sounds like a good idea. I really don't care to spend $40-60 on this type of game unless I find it on sale somewhere.
