Should I just get a 1080p monitor or go for a higher resolution?

I’m looking for a new monitor to use with my MacBook. I can’t decide whether to go for something that has a resolution of 1920×1080 and an HDMI input (like this Dell: http://lin.cr/06kg )or a higher resolution like 2048×1152 and no HDMI input (like this Samsung: http://lin.cr/06kh).

I don’t really have an immediate need for HDMI on a computer monitor, but I do think it could be useful at times. Most of the time I think having more screen real estate would be better than having the expandability of HDMI. What are your thoughts?
