Hi all, My mid-2007 (2.16 GHz Intel Core 2 Duo, 1 GB 667 MHz DDR2 SDRAM) experienced a crash hard drive last week. Not an upsetting experience because it was getting old and I had anticipated something like this, so I have everything stored on an external. Simply purchased/installed a new 320 GB HD and everything is running smoothly again. The reason I purchased the new HD was to up the resale value on the computer so I could upgrade to a new computer. I ordered an 11.6" MB Air last week from the Online Apple Store and much to my surprise and chagrin I do not like it. It really is a lovely little machine but I guess I prefer something with some substance. As soon as I fixed my old MB, I was back on it though I had a MB Air at my disposal as well. I'm sending the MB Air back, definitely. As far as my original MB is concerned, I am still running Tiger and thus running into a lot of compatibility issues with new versions of iTunes, Safari, well ... any software you can think of, really. It is blatantly obvious that I need to hop on the Snow Leopard train. However, I am concerned that the same thing is going to happen after I have Snow Leopard for a while and it becomes obsolete like Tiger-- the issues with upgrades etc. I know that my MB can't run Lion (or at least can't run it comfortably) with its 1 GB of RAM. That's where you guys come in. Thoughts on whether I should bite the bullet and upgrade to a new computer? I wouldn't mind a MB Pro, but I'm not lusting after one. I'm actually a bit wary since my brother has one and the logic board went out a month out of warranty (ouch). My concern is I will keep this MB so long that by the time I'm ready to move on it has no resale value or something will abruptly go haywire or the processor speed won't be up to handling programs that are a given for new models. I really don't use the computer rigorously, just Skype, Rosetta Stone, Word, and surfing the web. I think essentially I need to know this: - How long are these babies designed to last? I have not had one problem since I received it in June 2007, will this trend continue? - Should I upgrade RAM so I can install Lion? - Any other suggestions welcome. Thanks, and sorry for the wordiness. I just graduated with an English degree, so the need for excessive explanation is ingrained in me! Any advice/thoughts are appreciated.
